Answer:
Step-by-step explanation:
If a coordinate point (x, y) is dilated by a factor of k, the resulting coordinate will be (kx, ky)
Given
K = 7
Coordinates
A(-3, 2)
B(4, 2)
C(-1, -1)
If they are dilated by a factor of 7, the resulting coordinates will be;
A' (7(-3), 7(2)) = A'(-21, 14)
B' (7(4), 7(2)) = B' (28, 14)
C' (7(-1), 7(-1)) = C' (-7, -7)
Hence the co
