answer is 33

step-by-step explanation:

x:       y:  

-1         4

0         4

1         6

2         18

3         20  

the coordinates of a' are (-5, 10)

what i did is i   turned 2 1/2 into an improper fraction which is 5/2. then i multiplied this (the scale factor) by the coordinates of a which is (-2,4).

hope this : )
