Q:
# What are the coordinates of the image of vertex R after a reflection across the y-axis? -4,3 4,-3 -3,-4 3,4

Accepted Solution

A:

(β4, 3) (4, β3) (β3, β4) (3, 4)this is a rather simple yet complex concept the easiest way to solve these is to do the exact opposite. so in this instance it is refrcted across the y-axiss so we swap ONLY the x value NOT the Y ie (-4,3) would switch to (4,3) same thing would apply if it reflected across x-axis ex (-4,-3)If it reflect across orgin you change both signs. ex (4,-3)ie.(β4, 3) (4, β3) (β3, β4) (3, 4)changes to (4, 3) (-4, β3) (3, β4) (-3, 4)hope it helps
