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:

Hello there! :)

It's rational
it's an integer

x = 1 because -7(3x + 4) must be -49 so 3x + 4 must me 7 so x = 1
This is a more difficult one to explain. Let's start with the line to the right. It has a slope (m) of
= -1 and a y-intercept of +3 (continue the line to see where it crosses the y-axis). So, the equation of that line is: y = -x + 3 when x ≥ 2. This can also be written as y = 3 - x when x ≥ 2. The only option that has that equation is A.
