The points of the image after the reflection would be Z'(-1, 0), S'(-3, 2), and B'(-3, -3).
How to reflect the image ?
Reflecting a shape across the y-axis involves flipping it over the y-axis. This transformation changes the x-coordinates of the points, while the y-coordinates remain the same.
The rule for reflection across the y-axis is:
If a point has coordinates x, y, its reflection across the y-axis will have coordinates -x, y.
Apply this to the vertices of triangle BSZ:
Vertex Z (1, 0) Its reflection across the y-axis will be at (-1, 0).
Vertex S (3, 2) Its reflection across the y-axis will be at (-3, 2).
Vertex B (3, -3) Its reflection across the y-axis will be at (-3, -3).
The reflected triangle, will have vertices at Z'(-1, 0), S'(-3, 2), and B'(-3, -3)
