In this lecture, we'll see two ways of writing linear functions which will help us solve linear equations and problems involving parallel and perpendicular lines. The first way is the slope intercept form, y=mx + b, where m is the slope, and b is the y-intercept. This is useful when we need to graph a line. In the example, you'll see exactly how the slope intercept form will help you graph the function. The second way is the point slope form which includes a point on the line and the slope of the line and is related to the slope formula.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
