First you need the midpoint formula. (x1+x2 divided by 2)and (y1+y2 divided by 2) Which would look like this.. 13+-6=7 and 7 divided by 2 is 3.5.... 8+-6=2 And 2 divided by 2 is 1. so your answer is (3.5, 1)
Put the value of the letters with " over the original
So for A we have 3 in the front and 4.5 for A"
4.5/3 = 1.5
We can check if this is actually the scale factor but using the other numbers
The second numbers for A and A" are 6 and 9
6 * 1.5 = 9
So for point A it is 1.5
Use the same thing for G. That gives you 2
For B, you get 0.5
So the scale factors are 1.5, 2, and 0.5
The answer is b! Hope this helped
First question: B - 500/9
Second question: A - 6
