Question

Part A: Marguerite rented a truck at $125 for 2 days. If she rents the same truck for 5 days, she has to pay a total rent of $275.

Write an equation in the standard form to represent the total rent (y) that Marguerite has to pay for renting the truck for x days.

Answer 1

(2,125)(5,275)
slope = (275 - 125) / (5 - 2) = 150/3 = 50

y = mx + b
slope(m) = 50
use either of ur points...(2,125)...x = 2 and y = 125
now we sub and find b, the y int
125 = 50(2) + b
125 = 100 + b
125 - 100 = b
25 = b

so ur equation is : y = 50x + 25...but we need it in standard form

y = 50x + 25
-50x + y = 25
50x - y = -25 <== ur equation
