Answer:
(-6,6)
Explanation:
Step 1 identify coordinates of B
The coordinates of B are (-2,2)
Step 2 apply dilation by multiplying the x and y values of coordinate B by the scale factor (3)
(-2,2) -----> (-2 * 3 , 2 * 3 ) -------> (-6,6)
If ABCD is dilated by a scale factor of 3 the coordinates of B' would be (-6,6)
