Join Joan the chameleon in an exploration of lines and slope. You'll be drawing lines, calculating slope, using equations and more!

Use your knowledge about the slopes of parallel and perpendicular lines to solve some problems. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Given points that two lines go through or the graph of each line, classify the lines as parallel, perpendicular, or neither. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...

[Free Registration/Login may be required to access all resource tools.] This lesson covers determining if two lines are parallel, perpendicular, or neither and finding the equation of perpendicular lines to a given line.

The instructional activity teaches students about an important characteristic of lines: their slopes. Slope can be determined either in graphical or algebraic form. Slope can also be described as positive, negative, zero or undefined....

This activity has students discover the relationship between parallel and perpendicular lines and their slopes. After constructing these objects using CABRI Geometry II for the TI-89, slopes are measured. [Requires Adobe Reader.]

This activity is for use as a formative assessment tool after the introduction and overview of parallel and perpendicular slopes.

This site from the Northeast Parallel Architectures Center, Syracuse University has a very substantial discussion of math topics slope & line equations. The outline form is quite useful if you need to zero in on one aspect of...

Three resources for teaching slopes and equations of lines: a lesson with a formula for finding slope, different equations for lines, and several examples; a fourteen-question quiz covering slope, perpendicular and parallel lines, and...

This activity will help students understand the relationship between the slopes of parallel and perpendicular lines.

In this activity, students investigate how equations of parallel and perpendicular lines relate to each other. They use the drawing and measurement tools of Cabri Jr. to explore the slopes of lines. [Requires Adobe Reader.]

This site displays formulas and examples, pertaining to slope, for parallel and perpendicular lines.

Northeast Parallel Architecture Center, Syracuse University provides a brief definition of the slopes of parallel and perpendicular lines

Students use Cabri Jr. App to investigate the slopes and equations of parallel and perpendicular lines.

[Free Registration/Login may be required to access all resource tools.] Use their slopes to determine if two lines are parallel or perpendicular.

Students learn to develop the equation of a line from its graph. They also learn to write the equation of a line from the slope and the y-intercept, a point and the slope, and two points. They also investigate slopes of lines that are...

Given characteristics of two lines, such as slopes and equations, the student will determine whether the lines are parallel, perpendicular, or neither.

Students can use a graphing calculator to explore graphs of parallel and perpendicular lines. Students will find that parallel lines have the same slope and different y-intercepts and that the slopes of two perpendicular lines are...

This is an introductory lesson on graphing parallel and perpendicular lines. The students will have a good visual on how these lines relate to each other. This also illustrates how to determine equations in slope-intercept form of a line...

Washington State University provides a lesson on finding the slope of an equation and putting the equation into the desired form. The site also contains informatinon concerning parallel and perpendicular lines.

Twenty-five problems cover the topics of slope, parallel lines, perpendicular lines, and transversals in different settings. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the...

Learners demonstrate comprehension of advanced mathematical concepts in Algebra II. The questions check understanding on linear equations. Topics include writing equations of parallel and perpendicular lines.

Students will investigate the relationship of the algebraic slopes of pairs of lines to the graphical relationship between the lines.

Not only does this site show what the slope-intercept form is, but it helps you find the slope and the intercept of a line. There is also additional information on parallel lines, parametric form, and the distance between two points.
