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...

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.

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...

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.

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