If my weekly income was to increase by 15% next year. How much would I be earning in a week then? (was $750 a week)

862.50

Step-by-step explanation:

First find the amount of increase

750 * 15%

750 *.15

112.50

Add this to the original amount

750+112.50

862.50

We can see that the lines intersect at (-5,3) on the graph, so that eliminates choices B and D. Both A and C say that the first line is y=x+8, which is true. A says that the second line is y+x=-2, and after isolating y, we get y=-x+2, which seems correct. Do the same for C, and you will find that it says the other equation is y=x-2, which is not true because it must have a negative slope. So your answer will be choice A.
