Enter the slope and y-intercept of any line and it will be graphed for you. This site is great for becoming familiar with the concept of graphing and for checking your own graphs. Requires Java.

Given algebraic, tabular, and graphical representations of linear functions, the student will determine the slope of the relationship from each of the representations.

Practice the connection between the graphical representation of equations and their algebraic solutions. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

A nonlinear function that can be written on the standard form ax^2 + bx + c,where a is not = 0, is called a quadratic function. All quadratic functions hava a U-shaped graph called a parabola.

[Free Registration/Login Required] This flipchart should be used to help the students understand the concept of slope-intercept form and expand their knowledge of graphing linear equations.

Using this tutorial, you'll learn how to solve linear inequalities and show the solution via interval notation and graphing.

Learn how to find the x and y intercepts of a linear function, to graph the function using the intercepts, and to graph vertical and horizontal lines. The tutorial offers many examples with clear step-by-step examples.

Given a line, learn how to find the equations for lines that are perpendicular and parallel to it. This tutorial offers several example graphs and problems as well as practice problems for you to work through when you're ready.

Students compare their own hand/foot span to Shaquille O'Neal's, then graph the data & construct a best-fit line. They can then use the information to investigate the proportionality of the human body.
