This is a free lesson from our course in Algebra I

 In this lesson you'll introduce you to the linear equation, which basically is an equation whose graph is a line. For example, x + y - 2 = 0. Once you know the basics of linear equations, you'll move on to more advanced topics such as rerranging an equation to draw its graph, and to determine its slope and intercepts. At the end of each sub-skill you will have a number of practice questions with solution. (More text below video...)

(Continued from above) Steps to graph a linear equation:
• Find three ordered pair solutions. You do this by plugging in ANY three values for x and find their corresponding y values. It can be ANY three values you want, 2, -5, or even 10,000. Remember there are an infinite number of solutions. As long as you find the corresponding y value that goes with each x, you have a solution.
• Plot the points found in above step. Remember that each ordered pair corresponds to only one point on the graph. The point lines up with both the x value of the ordered pair (x-axis) and the y value of the ordered pair (y-axis).
• Draw the graph. A linear equation will graph as a straight line.
