If you are dilating a coordinate (a, b) by the scale factor "z", the new coordinate will be (za, zb).

It simply means that we multiply each cordinate, x and y, by the scale factor given.

Here,

The coordinate is (1, -8) and hte scale factor is "5". Thus, we multiply each coordinate by "5". So, it becomes:


\begin{gathered} (5*1,5*-8) \\ =(5,-40) \end{gathered}

The image is at (5, - 40)
