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. 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.
Yes. You can graph a line for any linear equation from any two points that fit the equation. So you can use the points (0, -75) and (15, 0) to graph the line representing the situation.
