The vertices of the reflection of the triangle over the line y = x is graphed at the end of the answer.
<h3>What is the rule for a reflection over the line y = x?</h3>
The rule for a reflection over the line y = x is given by:
(x,y) -> (y,x).
Hence we apply the rule to each vertex of the original figure to find the vertices of the reflected figure.
The vertices of the original triangle are:
(-1,1), (-3,1) and (-1,4).
After the reflection over the line y = x, the vertices will be given as follows:
(1, -1), (1, -3), (4, -1).
We just exchanged the x and y coordinates from the original vertices.
The original triangle, the reflected triangle, and the line are graphed at the end of the answer.
