The point (a,b) is the top of a rectangle. After a transformation, it maps to the point (-a,b+3), what type of transformations happened?

A. Reflection over the x-axis and translated 3 units down

B. Reflection over the y-axis and translated 3 units up

C. Reflection over the line y= -1 and translated 3 units left

D. Reflection over the y= 1 and translated 3 units right

Answer 1

Changing the a to -a reflects the figure over the y-axis.

Adding 3 to b raises the figure 3 units.
