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

Reflection about the yaxis has the transformation defined as:
T(x,y)→(x,y).
For example, the point (5,4) reflected about the yaxis 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.
