The 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. The points are (4,150) (2,100) and (0,50)

Which linear equation, in slope-intercept form, that models the total cost of the rental over time?

y = 50x + 25

y = 25x + 50

y = x + 50

y = 25x

y= 75x
