Linear FunctionA linear function can be written as y = mx + b and its graph is a straight line. Its slope represents a constant rate of change. y = mx + b (slope is m and y-intercept is b)Example: y = -43 x + 53556635441325(0,5)-4300(0,5)-432180590226060Identifying Slope and 4753610840105+1020000+14038600843915+1020000+13238500848995+1020000+12495550847090+1020000+1y-Intercept4776470873125-3020000-339052501714502409825889004038600885190-3020000-3390525055054503267075894715-3020000-3314325056134102533650885190-3020000-32419350561341031337258890042043361945004y-intercept, b, is 2, located at (0,2).slope = m = -31 = -3y = -3x + 200y-intercept, b, is 2, located at (0,2).slope = m = -31 = -3y = -3x + 255784754026535004768850400812000465264552990304652645-31750357298477679023037423544211001089025-5080001088390107263800Dependent/Independent VariableDetermine the distance (d) a car will travel going 55 mph.hd0015521103165d = 55h4558030280670dependent020000dependent-289560318135independent020000independentIndependent Variable32886657810500y = 2x + 7 x represents the independent variable(input values or domain)Dependent Variable19817873365500y = 2x + 7 y represents the dependent variable(output values or range)Connecting RepresentationsA bike rents for $4 plus $1.50 per hour. 366747562223300276225173933c = 1.5h + 400c = 1.5h + 4hc0415.52738.5410511.5Multistep Equations2x – 5.7 = -3.4x + 11.0423 (n + 9) = - 56n25 = 6p - 5-4Multistep Equation1559560876303x + 5 = -3 – x0200003x + 5 = -3 – x4486910170815000487680017081500041021002188210004084320170815000219392511347450022066256959600017919701147445001804035720725001822450336550006769107378700066992511582400068262532956500Verbal and Algebraic Expressions and EquationsVerbalAlgebraicA number multiplied by five5nThe sum of negative two and a number-2 + nThe sum of half a number and two is five times the number12y + 2 = 5yNegative three times a number is one-fifth the difference of four times the number and ten-3x = 15(4x – 10) Inequality-3(n – 4) < 0-3n + 12 < 0-3n < -12n > 4317500190500 0 1 2 3 4 5 00 0 1 2 3 4 5 508264156037 0 1 2 3 4 5 0 1 2 3 4 5 ................
