In this lesson, the teacher explains how to write equations of lines given different types of information about the line. The lesson begins with a discussion of slope-intercept form and demonstrates how to write equations in both slope-intercept and standard form. The teacher then provides examples of how to write equations given the slope and a point on the line. Finally, the lesson ends with an example of how to write an equation given the slope and a point that is not the y-intercept. Throughout the lesson, the teacher emphasizes the importance of checking work to ensure the equation is correct.
This video covers to how to write equations of lines given info about the line. This is part 18 of a series of videos about graphing lines.
