Question

The coordinates of trapezoid EFGH are E(8, 8), F(8, 10), G(1, 6), and H(4, 1). The image of EFGH under dilation is E'F'G'H'.

Answer 1

The coordinates of vertex F' would be (4,5). Since your original coordinates are twice the new coordinates, you'd have to divide the old coordinates by 2 to get the new coordinates of (4,5).
