Solution

Finding the image $(- 5, 5)$ of after a dilation by a scale factor of $4$ centered at the origin:
We know that the image of a point $(x, y)$ after a dilation by a factor of $d$ will be $(x d, y d)$ .
Therefore, the image of $(- 5, 5)$ after a dilation by a scale factor of $4$ will be $(- 5 \times 4, 5 \times 4) = (- 20, 20)$ .
