Question

Graphing a Reduction with Given Scale Factor
On a coordinate plane, a triangle has points (0, 0), (5, negative 5), and A (0, negative 5).

The triangle shown is a pre-image.

Apply a scale factor of 1/2 to find the image of point A.
(0, 0)
(3, –2.5)
(0, –2.5)
(0, –10)

Answer 1

(0, −2.5)

Scale factor 1/2 about the origin: multiply each coordinate of A(0, −5) by 1/2 → (0·1/2, −5·1/2) = (0, −2.5).
