Question

The coordinates of the vertices of figure ABCD are A(4, 2), B(2, 2), C(4, 3), and D(6, 2). Figure ABCD was dilated, with the center of dilation at the origin, to produce figure AꞌBꞌCꞌDꞌ with vertices
Aꞌ(32, 16), Bꞌ(16, 16), Cꞌ(32, 24), and Dꞌ(48, 16).
What was the scale factor of the dilation?

Answer 1

Take the point 4,2 for example, that converted to 32, 16.

What number multiplied converts each point to the other?

Answer 2

8

Answer 3

Correct.
