Sketch the Graph of a Circle

After correcting the last problem in his previous video, Sal explains how to graph quadratic functions. Those with difficulty graphing algebraic functions will find Sal's instruction and easygoing manner a welcome change from staring at...

This lecture continues reviewing linear equations and slope problems with several example problems. Those who didn't grasp the concepts during class might find this lesson helpful.

How many ways can you graph a quadratic? The video shows two approaches to graphing a quadratic expression that is initially in standard form. The first method finds the vertex using -b/2a. The second approach is to find (h,k). 

Do your learners prefer slope-intercept form when writing linear equations? The previous video in a series completes the same problems using point-slope form. This time, the instructor completes the problems using slope-intercept...

Starting with a quadratic equation in standard form, the instructor shows you how to rewrite the equation to vertex form. She shows step-by-step how to complete the square.

Kick off the school year with some math fun! New classmates share information about themselves by using graphs and interpreting data. The goal is to use a general graph shape, such as linear or exponential, and create labels for the axes...

Given a linear equation, rewrite it in different forms. No matter what form a linear equation is given in, it can be converted to the other forms. So that means every linear equation can be written in standard form, point-slope form and...

Watch this video and find out how to graph a quadratic equation when it's in intercept form! After going through the different forms of quadratic equations, an instructor leads viewers through an example problem. For the example problem,...
