Building on concepts from the Introduction video above (x, y table and intercepts), I graph a line and find its slope based on the graph. Then I graph the line just using the "slope-intercept" form. I go over three more equations for you to practice this. Comparing slope-intercept to "standard" form, I change an equation to slope-intercept and graph it. Next is a comparison of slopes: positive, negative, zero, and undefined (or no slope). I then present the slope formula for when you are given two points, calculating the slope and graphing the line to verify the slope. Then given a point and a slope, I graph a line. Lastly, I show how to know if lines are parallel or perpendicular based on slopes.
