Linear Equations

Graph linear equations in standard form with one coefficient equal to zero. The lesson plan reviews graphing lines in standard form and moves to having y-coefficient zero. Pupils determine the orientation of the line and, through a...

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...

Sal takes your class’ newfound (or growing) knowledge of graphs of lines to the next level. He presents a few word problems in which mathematicians need to understand how to use linear function graphs.

Viewers will learn how to graph lines, such as y=2x+1. The instructor emphasizes the relationship between the x and y variables, creates an x/y table, and finally graphs the equation. A total of three examples are given in this video.

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.

Graph a horizontal line that goes through a given point by first plotting that point on a coordinate plane. Then draw a straight line left and right that goes through the point, and you're done!

Draw a graph, label the units, plot the given point, then draw a straight line up and down through the given point. That is now the graph of a vertical line through a given point.

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.

How can you graph lines that don't seem to fit on the given graph? What makes a line straight? What does the rate of change mean when graphing a line? How do you know if a slope is positive or negative? How do you know if the graph of a...

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...
