Set up the transformation equations

Using the Translation Rule and Coordinate Transformations knowledge points
\[

$$\begin{aligned} &x - 6 = -4 \\ &y + 8 = 1 \end{aligned}$$

\]

Solve for the pre-image coordinates

Using the Coordinate Transformations knowledge point
\[

$$\begin{aligned} &x = -4 + 6 = 2 \\ &y = 1 - 8 = -7 \end{aligned}$$

\]
