Slope – Parallel and Perpendicular Lines
When solving problems, it is helpful to know the relationship that exists between parallel and perpendicular lines. In this lesson, you will learn about the slopes of parallel and perpendicular lines. Slope Properties for Parallel and Perpendicular Lines Jill just learned about the relationship betwe...

Thus, theproductof slopes of two perpendicular lines is equal to -1. Slope of Parallel Lines A set ofparallel linesalways have an equal angle of inclination. Let us suppose we have two parallel lines l1and l2in the coordinate plane, inclined at angle θ1and θ2respectively with the x-axi...
The slope of two (or more)parallel linesare equal since they all have the same angle of inclination: m1=m2 On the other hand, the slope of twoperpendicular linesare negative reciprocals of each other: m3=-$\frac{1}{m_4}$ There are two types of line equations involving the slope: ...
Want to find the slope-intercept form of a line when you're given a point on that line and another line parallel to that line? Remember, parallel lines have the same slope. If you can find the slope of that parallel line, you'll have the slo...
perpendicular. For example: Given two lines with slopes m1 and m2 The two lines are parallel if and only if their slopes are equal (i.e. m1 = m2) and they are not coincident (i.e. don’t lie on top of each other) or if they both are ...
