Exercise 9 Page 556

The image of each vertex must be plotted on the opposite side of the line of reflection while maintaining the same distance from the line.

Practice makes perfect

Before we begin, let's graph △ JKL and the line of reflection.

To reflect the triangle in x=-1, the image of each vertex must be plotted on the opposite side of the line of reflection while maintaining the same distance from the line.

Now, we can connect the reflected vertices to have the image of △ JKL.
