Explanation:

You want a graph of triangle ABC after dilation by a factor of 1/2 about the origin.

Dilation

Each coordinate is multiplied by the scale factor when dilation is about the origin:

(x, y) ⇒ (x/2, y/2) . . . . . . dilation by a factor of 1/2

A(4, -2) ⇒ A"(2, -1)

B(-2, -2) ⇒ B"(-1, -1)

C(-2, 2) ⇒ C"(-1, 1)

The graph is shown in the attachment.
