How would you put this in y=mx+b format

Question

Tara borrowed $1250 from her parents to buy a used car. Her parents do not charge any interest, and Tara makes $80 payments to them each month. What is the equation that models the money Tara owes?

Answer 1

Let y = the amount of money Tara owes

Let x = the number of months

y = 1250 - 80m
