Answer:
The answer is D.
Step-by-step explanation:
As said in the problem, we are labeling the total minutes used <em>x </em>and the total monthly income as <em>y</em>. 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:

2 = 2????
Thats what Im getting it from.
Since x is 2 then it would still be 2=2 in simple term.
Answer:

Step-by-step explanation:
After x=2, we see that the change in y over the change in x is positive since both variables increase with each other, so
is where the function is increasing.
Symmetry is the same as the one side of the graph but it is fliped on the X-axis
