Exploring Equations and Y-Intercept

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

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.

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.

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...

Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to more complex word problems.

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.

Parameters can move and change the steepness of a graph. Introduce the effects of changing the slope or the y-intercept of a linear graph. The resource shows how to incorporate changes on graphs and how they will move up, move down,...

So many methods and so little time! The efficient method of graphing a linear equation depends on what information the problem gives. Pupils learn three different methods of graphing linear equations. They graph equations using...

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...
