Question

R (3, 2), S (5, -2), and T (6, 0) are the coordinates of a triangle's vertices. If the triangle is reflected over the y-axis, what are the coordinates of the image? R'(-3, 2), S'(-5, -2), T'(6, 0) R'(-3, 2), S'(-5, -2), T'(-6, 0) R'(-3, -2), S'(-5, 2), T'(-6, 0) R'(3, -2), S'(5, 2), T'(6, 0)

Answer 1

Explanation:

Answer 2

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:

`(x,y)\to (-x,y)`

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).
