Slope of a Line Song

Here is the Slope of a Line song being performed.  I never got to finish teaching it.  As you can see in the video, it gets any sort of audience pumped up!  Of course, the lady doesn't do the Camel Walk in the video, but she does a lot of other cool things in it.

Learn it well, my young ones, learn it well.

The Slope of a Line

(Eye of the Tiger)

Rising up, as you look left to right

Yeah, that slope must be positive!

Vertical lines rise but never do run,

So that slope it must be undefined. ___

Parallel lines have the same slope,

So they never intersect.

(Spoken) You know it!

Slopes are opp-osite reciprocals;

Perpendicular lines have arrived.

It’s the slope of a line, a trick that I’ve been devised

Ra-tio of the rise to the run!

Take the difference of y over the difference of x,

And you’ve got it’s what we call slope___ of a line!!

Here is the link to the karaoke version, just in case you ever want to bus out in song:  ;)
