plz hurry 82 points help 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

Respuesta :

y = 25x + 50

$50 is a constant, whereas $25 is the daily rate and will vary

let x be the number of days rented, then

y = 25x + 50 ← in slope-intercept form


SchwarzschildRadius

So,

We need an equation which contains the points (0,50), and increases 25 for each day.

If we let days be x, then we can reason that for each day x, the price increases by $25x.

Thus, we get the equation y = 25x + 50, in which the cost starts at (0,50), and increases $25 each day (x).

Hope this helps!
