Question

The vertices of a triangle are A(−6, −3), B(0, 3), and C(−6, 0). Draw its image after a dilation with respect to the origin using a scale factor of 1/3. All I need to know is the points of the new triangle.

Thanks!

Answer 1

A'(-2, -1), B'(0, 1), C'(-2, 0)

Explanation:

When dilation is about the origin, the scale factor multiplies each individual coordinate.

A' = (1/3)A = (-6/3, -3/3) = (-2, -1) . . . . for example

The rest is mental arithmetic, since all given coordinate values are divisible by 3.
