The intent of this resource is to show algebra learners that there is a proportional relationship between two lines that have an intersecting point. As the coordinate x increases by a constant, the y coordinate also increases.  It...

Ninth graders are investigating slope of a line. The line is plotted using the slope and points on a line. They also write an equation given the right information. The use of a PowerPoint is part of the presentation.

Tenth graders use the mathematical program, MATHEMATICA and graph linear and quadratic equations. They sketch the graph of an equation manually. Students compare their sketch with the computer generated model of the graph.

Students practice reading a graph while doing story problems. They determine the x and y intercepts and calculate the slope. They also practice writing linear equations.
