Write a real-world situation for 7.50y + 9

Step-by-step explanation:

This equation is written in slope-intercept form, meaning that the value next to the variable (7.50) is the rate (slope) and the other number is the y-intercept (9).

So you can say that you mowed the lawn at $9 up front and 7.50 every hour (or half-hour whatever you want).
