How Do You Use a Graph to Reflect a Figure Over the X-Axis?
Use a graph to reflect the figure over the x-axis.
Summary
- The x-axis is the horizontal axis
- In this case, the line of reflection is the x-axis
- Count the distance from each chosen point in the figure to the line of reflection
- Each new point will be the same distance from the line of reflection as its original point, but on the opposite side
- Once each new point is plotted, connect the dots to find the image

Notes
-
- Sometimes you'll have multiple figures on a graph and you only have to reflect one
- So make sure you know exactly which figure you're going to reflect
-
- We want to reflect over the x-axis, so that's our line of reflection
-
- Find the distance from the line of reflection to the point you pick
-
- The new point is exactly the same distance from the line of reflection as the original point, but it's on the other side!
-
- Find the distance from each point to the line of reflection
- Plot a new point on the opposite side of the line of reflection using that distance
- Just connect the dots to find the image!
