Question

PLEASE HELP!

Jack got a job at the local sandwich shop so that he can save up enough money to buy a new bicycle. Jack started with $13, and he earns $8.50 an hour. If you were to graph a function to represent how much money, y, Jack has after x hours of work, what would be the x and y intercepts?

Select one:
A. x-intercept = 1.52, y-intercept = 13
B. x-intercept = 13, y-intercept = none
C. x-intercept = 13, y-intercept = 8.5
D. x-intercept = -1.52, y-intercept = 13

Answer 1

The answer is C.

Explanation:

The $13 he started off with is the y-intercept or the initial value, which is the point where x=0.

The x-intercept, or rate of change, is $8.50.

The slope intercept formula is y=mx+b, where m=8.5 and b=13.

The equation for this problem is y=8.5x+13.

So the answer is C
