Which scale factor will produce an expansion? 7/8 8/7 0.78 0.87 a dilation has a scale factor -2/3. what kind of result does the dilation have? opposite-side expansion opposite-side contraction same-side expansion same-side contraction dilate the point a(-7, 4) by a scale factor of 2. where is a' located ? (-9,6) (14,8) (-14,8) (-5,6) under a dilation, point a(-6,2) is moved to a'(9,-3). what is the scale factor? -2/3 -3/2 3/2 2/3

1. An expansion is produced if the dilation factor is > 1. The value that's greater than 1 is 8/7 so your answer is D.

2. This is an opposite side contraction as the factor is < 1 and it has a negative sign in front of it. So, your answer is A.

3. Basically, you just multiply everything by 2. So, it would be (-14, 8). Your answer is C.

4. The answer is -3.2 because the signs flipped (so it's negative) and magnitude increases (so it's > 1). Only B fits, so that's the answer.
