ANSWER
R'(-3, 2), S'(-5, -2), and T'(-6, 0).
EXPLANATION
The vertices of the given triangle are:
R (3, 2), S (5, -2), and T (6, 0).
We want to find the vertices of the image triangle after a reflection over the y-axis.
The mapping for a reflection over the y-axis is given by:
[tex](x,y)\to (-x,y)[/tex]
We just have to negate the x-coordinates.
Hence the image triangle will have coordinates
R'(-3, 2), S'(-5, -2), and T'(-6, 0).
