a gas station charges $9 for a drive - through car wash. write an equation that shows how the total car wash earnings, y, depends on the number of cars washed, x. do not include dollar signs in the equation. y =

Answer

Explanation:

Step1: Analyze the relationship

The total earnings (y) depend on the number of cars washed (x). Each car wash earns $9.

Step2: Write the linear equation

The equation for a linear relationship is (y = mx + b), where (m) is the slope (rate of change) and (b) is the y - intercept. Here, there is no initial amount ((b = 0)) and the rate (m=9). So the equation is (y = 9x).

Answer:

(y = 9x)
