a) Simply do 0.135(13.5%)*550 to get that his rent increases by $74.25.
b) Simply do 550+74.25 to get that his new rent is $624.25.
c) 624.25/550 = 1.135, or 100%+13.5%, the amount his rent increased.

I just used PEMDAS. It was easy.
For x= -1, find -1 on the x axis and draw a vertical line. For y=6, look for 6 on the y axis and draw a horizontal line.
