Writing Equations of Parallel and Perpendicular Lines

By the end of this section I can...

-write a linear equation of the line that passes through a given point, parallel to a given line

-write a linear equation of the line that passes through a given point, perpendicular to a given line

-prove if two linear equations are parallel, perpendicular, or neither
