Git: What Is the Slope Intercept Form of a Line?
Not only does this site show what the slope-intercept form is, but it helps you find the slope and the intercept of a line. There is also additional information on parallel lines, parametric form, and the distance between two points.
Texas Instruments
Texas Instruments: Linear Functions: Slope Intercept Form
Students learn to develop the equation of a line from its graph. They also learn to write the equation of a line from the slope and the y-intercept, a point and the slope, and two points. They also investigate slopes of lines that are...

Given a line, learn how to find the equations for lines that are perpendicular and parallel to it. This tutorial offers several example graphs and problems as well as practice problems for you to work through when you're ready.
Curated OER
Linear Functions
This site contains a short tutorial on point-slope, slope-intercept, and general form of linear equations. The site has an interactive graph of lines showing how the graph of a line changes when values of the linear equation change.
