This lesson on slope explains the slope concepts, demonstrates how to use the slope formula, shows how to find slope in horizontal and vertical lines, and how to use slope to find whether the lines through the pairs of points are...

Students learn that the slope is ratio of change in y to the change in x. They find the slope of a line using the slope formula, and examine the characteristics of lines with positive, zero, negative, or non-defined slope.

Given coordinate points, the student will use slope formulas to solve problems.

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

The student will derive and use the slope and midpoint formulas to verify geometric relationship that include parallelism and perpendicularity of lines. Then, the student will determine an equation of a line parallel or perpendicular to...

This CoolMath Resource will help students determine if lines are perpendicular by finding the slope, using the point-slope formula, and graphing.

This activity center is used to illustrate the difference between the slant height and the actual perpendicular height (of the given square pyramid) by the use of the distance formula.

This comprehensive study guide highlights the main terms and formulas needed to review lines in the coordinate plane. Examples are included.
