Which statement about the graph and charges is true? A. The graph that Larry created is a correct representation of his company's charges. B. The rate of change on Larry's graph is correct, but the y-intercept is incorrect C. The rate of change on Larry's graph is less than the rate his company charges. D. The rate of change on Larry's graph is greater than the rate his company charges.​

Answer 1

A. The graph that Larry created is a correct representation of his company's charges.

Explanation:

The equation for the services charges, y, is made up of the $10 initial service call fee plus $5 times the number of hours, x.

y = 5x + 10

Try any 2 values for x to see if they fits the graph.

x(hr) y($)

0 10

1 15

4 30

This is the line already drawn on the graph. Larry did everything correctly, so options B, C, and D are all false/incorrect.
