Graphing horizontal and vertical lines (8th grade math/algebra 1)

First, we learn the equations for horizontal and vertical lines. A horizontal line has an equation of the form y = b, and a vertical line of the form x = a.

Then we practice graphing lines, some of which are horizontal/vertical and some are not. Lastly, we practice graphing lines with given conditions.
