Question

Find the points which define the reflection of the figure given by A(3, 2), B(5, 8), and C(7, 3) reflected across the x-axis.

Answer 1

(2,1) reflected across the x axis is (2,-1). You should notice that the '2' didn't change.

Answer 2

Negate the y value, Keep x the same

Answer 3

Done. Good work. What do you get for (-3,-4)? Reflect it across the x-axis.

Answer 4

-3, 4?

Answer 5

You are now a champion x-axis reflector. :-)
