Graphing Using X and Y Intercepts

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

Extending his asymptotes lesson from the previous video, Sal shows viewers another example of graphing rational functions. This video is shorter than the previous one and could be shown in a single class session.

It's a straight line to understanding linear equations. Given a linear equation in standard form, scholars write the equation in slope-intercept form, identify the y-intercept, and use the slope to graph the line. An instructional video...

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...

Here's the final chance to learn about graphing linear equations. The last of a set of four videos shows scholars how to graph a linear equation in slope-intercept form. The example involves a positive slope and a negative y-intercept.

Parallel lines have no solution. Learners watch the presenter graph two linear equations to find the solution to a system of equations in an informative algebra video. They see that the two lines are parallel resulting in no solution to...

Given a linear equation, find the x-intercept and the y-intercept to graph the line. Not sure what to do or where to start? Watch this video and see the instructor break it down and make it understandable.

The instructor demonstrates graphically how to verify that a given point lies on the line of a given equation. She graphs a line in slope-intercept form, and then plots the point to verify if it is in fact, on the graph of the line.

Find the zeros on a given graph of a quadratic equation. What does this mean? It means to find the values at which the parabola crosses the x-axis. It seems pretty straightforward to be able to look at a graph and identify the points at...
