Learn how to graph linear equations in the form of y = mx + b using a calculator. Start by entering the equation into Y1 after pressing Y=. Use the ZOOM function and select (#6ZStandard) to view the graph. If the graph does not cross the y-axis, utilize the TRACE feature to check X and Y values. Adjust the WINDOW settings if necessary: increase ymax if the y-value exceeds 10 or decrease ymin if it's less than -10. Make sure to press GRAPH to see your updated graph.

1. Graphing Linear Equations Y = mx+ b
2. Calculator(set-up) Write equation in the form y = mx + b
Press the Y= and type equation into Y1
Press ZOOM . Then go to (#6ZStandard) and press ENTER
Note: if the graph does not cross the y axis then:
Press TRACE and look at bottom values of X and Y. If the y value is greater than 10 or less than -10, change the WINDOW
Press WINDOW.
If the trace value of y is greater than 10 then increase the ymax so it is larger than the trace value.
If the trace value of y is less than -10, then decrease the ymin so it is less than the trace value.
