11-88.

Examine the graphs in problem 11-86 again. Which, if any, have lines of symmetry? Copy each graph on your paper and show any lines of symmetry.

Remember that in order for an object to be symmetrical, it must be exactly the same on each side of the line of symmetry.

$y=1$ is a line of symmetry for graph (c).
