Graphing a Nonproportional Line This activity will help you meet these educational goals
Mathematical Practices—You will make sense of problems and solve them, reason abstractly and quantitatively, construct viable arguments and
analyze the reasoning of others, use mathematics to model real-world situations, use appropriate tools strategically, attend to precision and look for
and make use of structure.
Directions
Read the instructions for this self-checked activity. Type in your response to each question, and check your answers. At the end of the activity, write a
brief evaluation of your work.
Activity
In the first Lesson Activity, you derived an equation to model a car wash. The equation is y = 5x - 75. In this activity, you will graph this equation.
Question 1
Is it possible to graph the line that represents this equation by using two points found in the previous Lesson Activity. (15,0) and (0, -75)? Explain
your answer.
