What does this translation mean?
(x+5, y-2)
Move right 5 and down 2
100
What are the new coordinates?
(-3,-4)
100

After performing a reflection across the x-axis, what is the location of A'?
(-6,-3)
100
A transformation in which a figure slides but does not turn. Every point of the figure moves the same distance and in the same direction.
