Question

Write a function to describe the following scenario.

Jack starts with $192. He goes to the mall with his friends and spends $7 every hour.

Y= ? - ?x

Answer 1

The first number is the y-intercept or the starting point, which is 192. The second number is the rate of change, which is how much the starting number goes up or down per every 1 x value, which is -7 (negative because the y amount is going down bc he’s spending money). So the equation is y = 192 - 7x
