What's the Y-Intercept?

With problems applying to modern-day topics like Netflix and McDonald's, math whizzes analyze graphs and investigate the slopes. In this algebra worksheet, learners identify the slope and y-intercept of the given equations. They graph...

Challenge the class to determine the equation of a line. The 21st part in a 33-part series begins with a proof that every line is a graph of a linear equation. Pupils use that information to find the slope-intercept form of the...

After defining intercept, Sal solves a simple equation to identify each intercept and then plots the line on a graph. This video would quite nicely complement an introductory lesson on graphing.

Given a linear equation in standard form, find the x-intercept and y-intercept. In this video, Sal shows how to set x = 0 and solve the y-intercept and how to set y = 0 and find the x-intercepts.

Here is an introductory lesson to help you understand the slope of a line, whether positive or negative and the y-intercept's meaning. Several examples of changes in slope are shown on a graph, and the instructor relates them to how the...

The instructor uses a computer graphing program to illustrate how a line changes slope by manipulating the slope values in the equation. He also manipulates the y-intercept value to see where the line crosses the y-axis.

A clear introduction to slope-intercept form, this would be helpful for learners who are struggling with this concept. You might also provide this instructional video for class members to use as they work on homework or class work. A...

If you are given the value for slope (m), and the value for the intercept (b), all you need to do is remember what the slope-intercept form looks like. Y=mx+b. Then you just have to plug the given values into the slope-intercept line of...
