In this lesson, you'll review a few concepts and key features regarding lines. You'll be able to write equations of lines in three different ways (general form, slope-intercept form, and point-slope form) when given two points or one point and its slope. You'll also learn how to convert between the three forms. Additionally, you'll understand how to write vertical and horizontal lines In the end, you'll be able to build linear equations given word problems.
