This shows the method of using the point-slope form to write the equation, then solving that form for y to get y = mx + b.

The informaton given here can be entered directly into the y = mx + b or slope-intercept form. Then the y-intercept is used as a starting point where you apply rise over run to the given slope to…

Another demo on how to use the y-intercept to start a graph of a linear equation and then use the slope to find other points on the graph. It finishes with showing the line representing all of the…

Need the videos for finding tej slopes of parallel and perpendicular lines before viewing this one. This shows how to get the infromation needed for fulling in the point-slope form. You can leave…

Shows how to convert Ax + By = C to y = mx + b then what and why the slopes for parallell and perpendicular lintes are what they are.

Demonstrates how to graph this tyep of equation by finding three points, but also how you can find just one point and use the slope "m" to find others.
