How Do You Write an Equation of a Line in Slope-Intercept Form If You Have the Slope and the Y-Intercept?
If you are given the value for slope (m), and the value for the intercept (b), all you need to do is remember what the slope-intercept form looks like. Y=mx+b. Then you just have to plug the given values into the slope-intercept line of...

What are Parallel Lines?
Parallel lines never intersect. That's right, NEVER! They are in the same plane but never touch. The instructor illustrates many types of lines and shows you how parallel lines don't ever cross.
