How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope. If the slopes of two lines are equal, they will never intersect.

How do you write the equation of a line parallel to a given line?

Back

To write the equation of a line parallel to a given line, use the same slope as the given line and the point through which the new line passes.

How do you write the equation of a line perpendicular to a given line?

Back

To write the equation of a line perpendicular to a given line, use the negative reciprocal of the slope of the given line and the point through which the new line passes.
