Compare two different proportional relationships represented in different ways.solve linear equations in one variable.give examples of linear equations in one variable with one solution, infinitely many solutions or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a andb are different numbers).solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.

Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.**describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear).

Compare two different proportional relationships represented in different ways.use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mxfor a line through the origin and the equation y = mx+ b for a line intercepting the vertical axis at b.solve linear equations in one variable.a.give examples of linear equations in one variable with one solution, infinitely many solutions or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (wherea and b are different numbers).b. solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.interpret the equation y = mx+ b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1),(2,4) and (3,9), which are not on a straight line.3 weeks3.2Determining Rate of Change – Table3.3Determining Rate of Change - Context 3.4Determining Rate of Change – Equation3.5Determining y-intercepts 3.6 Determining Rate of Change and y-interceptMultiple Representations of Linear Functions4.1Analyzing Problem Situations using Multiple Representations2 weeksIAB Functions4.2Introduction to Standard Form of a Linear Equation4.3Connecting the Standard Form with the Slope-Intercept Form of Linear Functions4.4Intervals of Increase, Decrease and No Change4.5 Developing the Graph of a Piecewise FunctionPart IIThe second part of Course 3 focuses on Geometry. Students apply and extend their understanding of numbers and their properties to include real numbers. Students solve a variety of problems using the Pythagorean Theorem.

Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually and convert a decimal expansion which repeats eventually into a rational number.use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram and estimate the value of expressions (e.g., π2). use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = p, where p is a positive rational number.

Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.solve real-world and mathematical problems leading to two linear equations in two variables. For example, given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair.2 weeks11.2Graphs and Solutions of Linear Systems11.3Using Substitution to Solve a Linear System I11.4Using Substitution to Solve a Linear System IISolving Linear Systems Algebraically12.1Using Linear Combinations to Solve a Linear System I12.2Using Linear Combinations to Solve a Linear System II12.3Using the Best Method to Solve a Linear System 12.4Using Graphing Calculators to Solve Linear Systems12.5Using the Graphing Calculator to Analyze SystemsProperties of Exponents13.1Powers and Exponents8.EE.18.EE.38.EE.48.NS.1know and apply the properties of integer exponents to generate equivalent numerical expressions.

Students are introduced to bivariate data through the use of tables and scatter plots. Students determine a line of best fit for a data set and use that line to make predictions.Data in Two Variables15.1Using Scatter Plots to Display Bivariate Data8.SP.18.SP.28.SP.38.SP.4construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association and nonlinear association.know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line and informally assess the model fit by judging the closeness of the data points to the line.use the equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept. For example, in a linear model for a biology experiment, interpret a slope of 1.5 cm/hr as meaning that an additional hour of sunlight each day is associated with an additional 1.5 cm in mature plant height.understand that patterns of association can also be seen in bivariate categorical data by displaying frequencies and relative frequencies in a two-way table. Construct and interpret a two-way table summarizing data on two categorical variables collected from the same subjects. Use relative frequencies calculated for rows or columns to describe possible association between the two variables. For example, collect data from students in your class on whether or not they have a curfew on school nights and whether or not they have assigned chores at home. Is there evidence that those who have a curfew also tend to have chores?Mathia1 week15.2Interpreting Patterns in Scatter Plots15.3Connecting Tables and Scatter Plots of Collected DataLines of Best Fit16.1Drawing the Line of Best Fit2 weeksPerformance TaskICA 16.2Using Lines of Best Fit16.3Performing an Experiment16.4Correlation16.5Using Technology to Determine Linear Regression EquationsNon-linear and Categorical Bivariate Data17.1Scatter Plots and Non-Linear Data1 week 17.2School Sports17.3School Sports (cont.)14.5Interpreting ResultsNot part of WVCCSS—highlighted sections ................
