How to Graph Linear Equations With a Calculator

When attempting to solve linear equations, which include variables and constants, it can be helpful to see a visual representation of the equations on a graph. With a graphing calculator, you can enter any linear equation and have the device draw a virtual graph of it. To graph a linear equation on your calculator, the equation's formula must be in the "y=" format.

Things You'll Need

• Graphing calculator

Instructions

1. Turn on the graphing calculator and press the "Zoom" key.

2. Select the "Zoom Standard" option to reset your calculator's graph to the basic view.

3. Press the "Y=" key to access the equation entering screen. Then type the right side of the linear equation you want to graph, using the "X" key to represent the equation's variable.

4. Press the "Enter" key to save the equation and enter any additional linear equations for the graph.

5. Press the "Graph" key and wait for the calculator to draw each of the linear equations on the grid.
