Question

Reflection over the y-axis Example 2 Original Point Coordinates Image Point Coordinates A (-8,2) A B (-4,9) B C (-3,2) C'

Answer 1

We have to reflect the 3 points shown over the y-axis.

The simple rule for reflecting over y-axis:

• keep y coordinate same

,

• negate the x coordinate

So,

(x,y) would become (-x,y)

Now, let's reflect the 3 points:

A(-8,2) would become A'(8,2)

B(-4,9) would become B'(4,9)

C(-3,2) would become C'(3,2)
