Reflections
Coordinate Rules
Coordinates will change depending on the line
over which it is reflected. (x. y) represents the
pre-image coordinate. Reflections occur mostly
over the x & y-axes, the line y-x and the line y--
x. But, it is common to reflect over other
horizontal/vertical lines as well.

Graph APQR with vertices P(1, 3), Q(4, 1),
and R(1, 1). Reflect APQR over the x-axis, y-
axis, the line y=x, and the line y=-x. Use a
different color for each.
