How to Reflect Points on a Coordinate Plane
First, Know...
Reflecting points across an axis is like creating a mirror image.

The x-axis is the horizontal axis.

The y-axis is the vertical axis.

Y-AXIS
When reflecting over the y-axis the sign of the x-value changes. The sign of the y-value never changes.

X-AXIS
When reflecting points over the x-axis, the sign of the y-value changes. The sign of the x-value never changes.
Examples
(2,1) reflected over the x-axis becomes (2,-1).

(4,-3) reflected over the x-axis becomes (4,3).
Example:
For example: Create one half of a butterfly on the positive side of the x-axis, and reflect the half of the butterfly over the y-axis so that you have created a complete butterfly.
Hint:
The origin point will stay at (0,0) when reflecting across the y or x-axis.
Practice
Try to reflect (3,5) over the x-axis .
Answer:
(3,-5)
Examples
(4,2) reflected over the y-axis is (-4,2).

(-5,1) reflected over the y-axis is (5,1).
Practice
Try to reflect (3,3) over the y-axis.
Answer:
(-3,3)
Create a drawing on graph paper using
reflection and symmetry.
