How to Graph Linear Equations on a Solver
Linear equations are equations that can come in the form of: y = mx + b, where m is the slope, x is the variable and b is the y-intercept. Mathematicians refer to this equation as the slope-intercept form of a linear equation. Here are several examples of some linear equations: 2x + 5, 3x, and 4x - 6. In the case of the first equation, 2 is the slope and 5 is the y-intercept of the equation. To calculate the slope of the equation, find the change in y and divide that by the change in x.

Enter in your linear equation in the rectangle labeled "Plot." For example, you can enter in an equation like 6x + 3. Set the minimum points for the x axis as -10 and the maximum as 10 and do the same for the y axis; that way you will be able to see the entire graph.
