Two very clear examples of point-slope form are given in this Purplemath lesson. One example begins with the slope and a point and the other example begins with two points. Includes interactive widget for practice determining a linear...

A tutorial on slope with many step-by-step examples. The tutorial clarifies what slope is, how to find slope between two points on a graph, and how slopes of parallel and perpendicular lines are related.

Explore the slope-intercept and point-slope forms of linear equations and how to graph them on this webpage.

Learn how to graph lines with two methods: using x- and y-intercepts and using point-slope form.

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

Here is a site that clearly and thoroughly explains many topics surrounding the slope of a line, including slope of horizontal, vertical, parallel, and perpendicular lines in addition to the formula and concept of slope. There are...

Slope-intercept form of a line is shown in formulas and examples with this Purplemath lesson. There are examples of slope-intercept with the slope and a point and with two points. Includes interactive widgets for exploring concepts.

Eighth graders work with slopes and similar triangles in this problem and will learn why the calculated slope will be the same for any two points on a given line. Aligns with 8.EE.B.6.

This lesson will use a slide presentation to facilitate teaching students how to find the slope of a line when given the graph of the line or two points. Students will interact with the presentation in two ways: first, by taking notes...

Three different lessons demonstrate how to write linear equations. The equations found from two points, slope and a point, and slope and y-intercept are all featured. The lessons have an overview, materials, procedures, and evaluation...

Demonstrates, step-by-step and with illustrations, how to use slope and the y-intercept to graph straight lines.

Here is a site that clearly and thoroughly explains linear functions and the equation of a straight line. There are example problems solved, problems for the student to attempt, and answers to the student problems. Point this site out to...

This lesson plan helps young scholars understand how to graph ordered pairs on the coordinate plane. Lots of resources are available to teachers and students at this website.

Use your knowledge about the slopes of parallel and perpendicular lines to solve some problems. For example, what's the equation of the lineperpendicular to y=3x-3 and passes through the point (-8, -2).
