Question

If ΔABC is reflected across the y-axis, what are the resulting coordinates for points A', B', and C'

sketch the reflection on the cordinate plan

Answer 1

Explanation:

Reflection across the y axis changes the x value.

Reflection across the x axis changes the y value.

This is counterintuitive, but it is correct.

A'

(-1,6)

B'

(-2,1)

C'

(-5,2)

Do you see what happened. All the values for x become - values because you are moving an equal distance in the -x direction
