Question

The rental rate for a hedge trimmer has a one time fee of $20 plus $30 for each day of the rental. The graph shows points representing the total cost of the rental. A function graph of a ray with three points (0,20), (2,80) and (3, 110) with an x axis of zero to five Days and a y axis of zero to one hundred forty in Total Cost Which linear equation, in slope-intercept form, that models the total cost of the rental over time? y = 2x + 80 y = 20x + 30 y = 30x + 20 y = 30x y = 20x

Answer 1

The linear equation in slope - intercept form that models the total cistern of the rental over times is 
y= 30x + 20
