​Objective:

​To relate slope to parallel and perpendicular lines.

​Point-Slope Form:

​

​Distribute and solve for y to write the equation in slope-intercept form.

​

​Given a line and a point not on the line, there is exactly one line through the point that is parallel to the given line.

​

​​Given a line and a point not on the line, there is exactly one line through the point that is perpendicular to the given line.

​Writing equations of parallel lines:

​Let's take a look in Desmos:
