Question

Determine the cordinates of the point located at (-3,5) after the described transformation

Dilation by a scale factor of 4 and a reflection over the x-axis

Answer 1

(-12, -20).

Explanation:

A dilation of factor 4 moves (-3, 5) to (-3*4, 5*4) = the point (-12, 20).

A reflection over the x-axis is (x, y) ------> ( x, -y).

So ( -12, 20) goes to (-12, -20).
