Write equations in point-slope form given two pairs of values, and convert the equation into slope-intercept form.

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

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...

This site from the University of North Caroline at Wilmington provides great information on the lines in a plane. The information that is given is in-depth and complete, touching on the slope of a line, equations of lines, and linear...

Test your knowledge of coordinate geometry by taking this twenty question multiple-choice practice test. Use a graphing calculator to help with any graphing problems and check your answers at any given time throughout the test.

A brief overview of three methods used to graph lines is presented through examples. Slope-intercept, point-slope, and intercept form are demonstrated step-by-step along with a review of the formula for finding the slope of a line.

Medhavi suspects that there is a relationship between the number of text messages high school students send and their academic achievement. To explore this, she asks a random sample of 52 students at her school how many text messages...

In this self-guided unit, you will read Romantic and Transcendental literature and you will practice the art of persuasion using rhetorical devices, appeals, and refutation while avoiding logical fallacies. By the end of the unit, you...

These examples show how to write linear equations from different types of information. There are even real-world examples dealing with air pressure, sea urchins, and measurement conversions.

The tangent to a curve is always found at a certain point along the curve. Often you will be asked to find the normal to a curve at a point. View an example on this site.

This unit is all about linear relationships and functions.

This applet allows you to plot up to fifty points and it will display a best fit line and give you the slope of that line.

Discussion of common fallacies, along with definitions, examples, and tips on avoiding them.
