This webpage allows you to drag and drop about 10 points onto a cartesian graph and also connects the points as a line segment

In this Early Edge video lesson, you'll learn more about Number Families, so you can be successful when you take on high-school Math & Arithmetic.

In this Early Edge video lesson, you'll learn more about Two-Step Equations, so you can be successful when you take on high-school Math & Algebra.

This interactive online tool enables students to simultaneously visualize and manipulate three linked representations of a distance-rate-time problem. The side-by-side tool format features two airplanes (each flying at a constant speed) on merging jet routes, the corresponding distance-vs.-time graphs, and the corresponding linear equations.

Excellent site showing examples of algebra, trig, calculus, differential equations, and linear algebra.

Need help solving systems of linear equations? In this video, a Tutor.com algebra tutor uses the substitution method to solve a system of linear equations, and shows you how to use graphing to make sure you don’t get tricked by systems of parallel lines that have no solution. You’ll graph the linear equations, find their point of intersection, solve them using substitution, and check your work to make sure it all makes sense.
