Finding the slope with two points

On the CSTs and the CAHSEE you are expected to be able to find the slope of a line with two points.  Here we walk through the process.  This lesson is unedited you should be able to find a mistake (hint: 7-2 does not equal 4 so where's the mistake?)

Finding the Slope of a Line with Two Points

Pythagorean Theorem

It is CAHSEE time!  One of the items that always makes it appearance on the CAHSEE is the Pythagorean Theorem.  For any right triangle the squares of the lengths of the sides is equal to the square of the hypotenuse. Here we share a proof of this theorem.

Explaining the parts of the coodinate plane

This video is timely as we start to think about the California Standards Tests (CSTs) coming up.  We are reviewing the parts of the coordinate plane and how to graph a point.

This also is our first attempt to convert and publish our video in an MP4 format.  Please let us know if you can view this movie on any mobile devices.
