Question

A preimage (2,-3) is translated to (3,2). What type of transformation has occured?

Answer 1

Reflection.

Explanation:

The reflection of the point (x,y) across the x-axis is the point (x,-y).

The reflection of the point (x,y) across the line y = x is the point (y, x).

Given the preimage (2,-3).

• Step 1: Reflect (2,-3) accross the x-axis, to obtain: (2,3)
• Step 2: Reflect (2,3) accross the the line y = x to obtain: (3,2)

Therefore, the type of transformation that has occured is Reflection.
