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
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.
