In this ged math/algebra video I explain the following: Given a graph write the equation of a line in the form y=mx+b. This is also referred to as the slope intercept form. I also go over how to write the equation of the two special cases i.e horizontal and vertical lines.

0:00 - Example 1
13:26 - Example 2
19:30 - Example 3
23:21 - Example 4 (horizontal lines)
26:57 - Example 5 (vertical lines)
