Graphing Using its Slope and y-Intercept
To graph using its slope and y-intercept, the equation must first be rewritten in slope-intercept form before applying the six-step procedure.
Step 1 — Find the slope-intercept form. Starting with , subtract from both sides:
Divide both sides by :
Step 2 — Identify the slope and y-intercept. The slope is and the y-intercept is .
Step 3 — Plot the y-intercept. Mark the point on the coordinate plane.
Step 4 — Identify the rise and the run. The rise is (up units) and the run is (right units).
Step 5 — Count the rise and run to mark the second point. Starting at , move up units and right units to reach .
Step 6 — Connect the points with a line. Draw a straight line through and .
This example illustrates the full procedure when the equation starts in standard form rather than slope-intercept form: solving for is the essential first step before the slope and y-intercept can be read off and used for graphing.
