The original 12.50 is how much she pays each month regardless of rented movies, it is the 0 value and doesn't change. Each rented movie costs 5.25 (17.75-12.50=5.25) and that value would be multiplied by the amount of movies she rents that month, and then added onto the original base value.

Next month paid $12.50 for Prime and 7 movies totalling $36.75
Hello the equation is y = ax+b a the slop a = 4 y = 4x+b the line <span>passes through (3, -10) : -10 = 6(3)+b b = -28 </span>the equation is y = 6x-28
