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

  1. The x-axis is the horizontal axis
  2. In this case, the line of reflection is the x-axis
  3. Count the distance from each chosen point in the figure to the line of reflection
  4. Each new point will be the same distance from the line of reflection as its original point, but on the opposite side
  5. Once each new point is plotted, connect the dots to find the image

Notes

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