Step-by-step explanation:
not sure sorry
Answer: expense that you must pay and is the same amount each month
We can determine the number of solutions from the slope intercept form of the equations.
Slope intercept form of equation 1 is:

Slope intercept form of second equation is:

The slope and the y-intercept of both equations are the same. This means, the two lines are lying over each other and hence they infinite number of solutions.
So, the correct answer is option C
It would sure help a lot if I could take a peek at the drawings of the triangles.
