On graph paper, or on the sketchpad, reflect the preimage across the line x equals 1?

To reflect the preimage across the line x = 1, you would essentially flip the image over the line x = 1. Here is how you can do it on graph paper:

1. Draw a line x = 1 on the graph paper.
2. Draw the preimage on one side of the line x = 1.
3. For each point on the preimage, measure the distance from the point to the line x = 1 and then move the same distance on the other side of the line to plot the reflected point.
4. Connect the reflected points to form the reflected image.

Alternatively, you can use a sketchpad or a digital drawing tool to reflect the preimage across the line x = 1 by selecting the preimage, copying it, and then flipping it horizontally over the line x = 1 to create the reflected image.
