Unit 3: End-of-Unit AssessmentSelect all the points that are on the graph of the line y=5-12x.(0,5)(0,10)(2,4) (5,0)(10,0)For two weeks, the highest temperature each day was recorded in four different cities. Lines l, m, n, and p?are graphs of the temperature over time in Lubbock, Memphis, New Orleans, and Phoenix. Which statement is true?The high temperature in Lubbock increased as time passed.?The high temperature in Memphis decreased steadily.Initially, the high temperature?was warmer in Phoenix than in Memphis.The high temperature in Phoenix rose faster than the temperature in New Orleans.?Jada earns twice as much money per hour as Diego. Diego earns twice as much money per hour as Lin. Select all the?graphs that?could represent how much Jada, Diego, and Lin earn for different amounts of time worked.420243010858500?427545510604500??Find an equation for each line.Line L y=Line M y=Line N y=Line P x=Three runners are training for a marathon. One day, they all run about ten miles, each at their own constant speed.85090018097500This?graph shows how long, in minutes,?it takes Runner #1 to run d miles.The equation that relates Runner #2’s distance (in miles) with time (in minutes)?is t=8.5d.Runner #3’s information is in the table: distance (miles)Time (minutes)2184366548721090Which of the three runners has the fastest pace? Explain how you know.A cell phone plan costs $200 to start. Then there is a $50 charge each month.What is the total cost (start up fee and monthly charge) to use the cell phone plan for 1 month?What is the total cost for x months?Graph the cost of the cell phone plan over a period of two years, using months as the units of time. Be sure to label your axes and?scale them by labeling?each gridline with a number.Is there a proportional relationship between time and the cost of the cell phone plan? Explain how you know.Draw a line parallel to the line you graphed that goes through the point (0,350). Suppose that this line represents the pricing plan for another company. What is the startup fee and monthly cost for this plan? ................
