Answer:
2
Explanation:
Length of side AB: side AB is the hypotenuse is 3, 4, 5, right triangle, so its length is 5.
You can also use the distance formula for points (-2, -2) and (2, 1) to get a distance of 5.
Length of side A'B': side A'B' is the hypotenuse is 6, 8, 10, right triangle, so its length is 10.
You can also use the distance formula for points (-4, -4) and (4, 2) to get a distance of 10.
scale factor = (new linear distance)/(old linear distance)
scale factor = 10/5 = 2
