Point P has coordinates (4, 8). After a reflection across the line x = 1, what are the coordinates of point P'
----
Plot the point.
Draw the line x = 1
------
Notice that P is 3 to the right of x = 1
So the x-coordinate of P' is 1-3 = -2
---
Notice that P is at height = 8
So P' is also at height = 8
---
P': (-2,8)
