Answers:
A ' = (-6, -6)
B ' = (-3, 7.5)
C ' = (6, 4.5)
D ' = (9, -3)
======================================
Explanation:
For each point, you multiply each coordinate by the value 1.5
For point A we have x = -4 turn into 1.5*x = 1.5*(-4) = -6. The same happens to y as well (since y = -4 is what we start with). So that shows how to get (-6,-6)
Point B is the same story, but different numbers. We have x = -2 turn into 1.5*x = 1.5*(-2) = -3, and we have y = 5 turn into 1.5*y = 1.5*5 = 7.5; showing how B(-2,5) becomes B ' (-3, 7.5)
Similarly, C is at (x,y) = (4,3). So 1.5*x = 1.5*4 = 6 and 1.5*y = 1.5*3 = 4.5 placing C ' at (6, 4.5)
Finally, for point D we have x = 6 and y = -2 pair up. Therefore, 1.5*x = 1.5*6 = 9 and 1.5*y = 1.5*-2 = -3. So (6,-2) dilates to (9,-3)
