What are horizontal or vertical line graphs?

A horizontal has the equation y=b with b any constant number
A vertical has the equation x=c with c any constant number

A normal linear equation is mostly of the form y=mx+b
where m is the slope. In a horizontal graph, the slope is 0.
The b (called the y-intercept) tells you where the graph crosses the y-axis.

For the vertical graph a similar story goes and c is called the x-intercept.
