Plz hurry 82 points plzthe rental rate for a power washer has a one time fee of $50 plus $25 for each day of the rental. the graph shows points representing the total cost of the rental. which linear equation, in slope-intercept form, that models the total cost of the rental over time? y = x + 50 y = 50x + 25 y = 25x y = 25x + 50 y = 75x

The equation is y=25x+50

Step-by-step explanation:

$50 is the fixed rate that you have to pay no matter how long you rent the washer. So it is a constant (y-intercept) added to the total cost.

$25 is the per-day charge and the total will depend on how long you have the washer. So it depends on the number of days and the multiplier (slope) is 25

Combining the total cost of rental over time: y=25x+50

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
