A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $155 for 100 minutes of us

Answer:

The answer is D.

Step-by-step explanation:

As said in the problem, we are labeling the total minutes used x and the total monthly income as y. This means that in the graph we will be making the y-axis should represent the total monthly charges, and the x-axis should represent the total minutes.

Thus the graph should go through points (100,155) and (200,245) and its slope is:

$\frac{245-155}{200-100} =0.9.$
