Graphing by Plotting Points
To graph the equation using the Point-Plotting Method, follow the three standard steps:
Step 1 — Find three solution points. Since is already isolated, choose convenient values for and compute :
- : , giving
- : , giving
- : , giving
Step 2 — Plot the points. Mark , , and on a rectangular coordinate system. All three points fall on the same straight line, confirming the calculations are correct.
Step 3 — Draw the line. Connect the three points with a straight line, extend it across the grid, and add arrows on both ends. The resulting line is the graph of .
