Answer:
translates the figure 7 units left and 8 units down
Explanation:
You know that increases in x-coordinate move a point to the right. So, decreasing the x-coordinate by 7 units will move a point to the left by 7 units.
Likewise, increasing the y-coordinate will move a point up. So, decreasing the y-coordinate by 8 units moves the point down 8 units.
The transformation ...
(x, y) ⇒ (x -7, y -8)
translates the figure 7 units left and 8 units down.
