Question

An auto mechanic charges (C) an initial fee of $50 and then $40 per hour. The graph of this model would be:

a curved line that increases but then decreases.

a straight line that decreases only.

a straight line that increases only.

None of these choices are correct.

Answer 1

The graph of this model would be a straight line that increases only option third is correct.

What is a line graph?

A line graph is a graph made up of segments of straight lines that connect the depicted data points.

We have:

An auto mechanic charges (C) an initial fee of $50 and then $40 per hour.

Let T be the total fee and h is the number of hours

T = 50 + 40h

The above equation represents a graph of a straight line as the slope of the line is positive.

m = 50

Thus, the graph of this model would be a straight line that increases only option third is correct.
