Triangle XYZ has vertices X(- 1, 1), Y(- 3, 1), and Z( -2, 5). Reflect triangle XYZ in the y-axis. Find the vertices of the image

• pre algebra -

Reflection about the y-axis has the transformation defined as:
T(x,y)→(-x,y).
For example, the point (5,4) reflected about the y-axis becomes (-5,4), according to the rule.

Apply the rule to all three vertices (in the same order) of the given triangle to get the image.
