Answer

A' (-8, 4)

Step-by-step explanation

When a figure, that is on the coordinates system is dilated (that is, enlarged or reduced) with respect to the origin, the new coordinates of its edges is simply a product of its old coordinates and the scale factor.

For this question, the coordinates of A is (-2, 1) and the dilation of the triangle ABC is by a scale factor of 4.

So, the new coordinates of A will be calculated thus

A (x, y) = A' (x × scale factor, y × scale factor)

A (-2, 1) = A' (-2 × 4, 1 × 4) = A' (-8, 4)

Hope this Helps!!!
