Question

A triangle has vertices at A (1, 3), B (4,2), and C (3,8). Which transformation would

produce an image with vertices A' (2,6), B'(8,4), C'(6,16)?
A rotation so' counterclockwise.
A dilation with a scale factor of 4.
A rotation 90° clockwise.
A reflection over the x-axis.
A dilation with a scale factor of z.

Answer 1

A dilation with a scale factor of 2

Explanation:

Each image coordinate is double the corresponding pre-image coordinate. That means the figure was dilated by a factor of 2.
