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.

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

Responses

y = 2x + 80
y, = 2, x, + 80

y = 30x + 20
y, = 30, x, + 20

y = 20x
y, = 20, x

y = 20x + 30
y, = 20, x, + 30

y = 30x
y, = 30, x

Answer 1

i think its 30x + 20

Answer 2

Correct Answer: I believe the answer would be y = 20x + 30
Explanation: 20 would be next to x because it is the slope of the graph and is the one time rental fee in the problem. As for 30 it says plus $30, so 30 would be after the plus sign. And we know that it can't just be y=20x or y=30x...

i hope you understand and I hope I could help
