In this interactive worksheet, 8th graders review how to calculate the slope of a line, then solve 10 problems, given 2 points. Students may click for further information, on finding a slop of a line.

In this algebra worksheet, learners identify the slope and y intercept of lines. They compare the slope of perpendicular and parallel lines and find the missing slope. There are 6 questions with an answer key.

In this Algebra II worksheet, 11th graders use an online quadratic equation solver to find the zeros of a quadratic.  The one page interactive worksheet provides one worked example and the equation solver. 

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.

Transformations of linear functions, with links between the symbolic and graphic forms, can be powerful tools to help students overcome conceptual hurdles in algebra.
