Graphing 4x3y=124x - 3y = 12 Using its Slope and y-Intercept

To graph 4x3y=124x - 3y = 12 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 4x3y=124x - 3y = 12, subtract 4x4x from both sides:

3y=4x+12-3y = -4x + 12

Divide both sides by 3-3:

y=43x4y = \frac{4}{3}x - 4

Step 2 — Identify the slope and y-intercept. The slope is m=43m = \frac{4}{3} and the y-intercept is (0,4)(0, -4).

Step 3 — Plot the y-intercept. Mark the point (0,4)(0, -4) on the coordinate plane.

Step 4 — Identify the rise and the run. The rise is 44 (up 44 units) and the run is 33 (right 33 units).

Step 5 — Count the rise and run to mark the second point. Starting at (0,4)(0, -4), move up 44 units and right 33 units to reach (3,0)(3, 0).

Step 6 — Connect the points with a line. Draw a straight line through (0,4)(0, -4) and (3,0)(3, 0).

This example illustrates the full procedure when the equation starts in standard form rather than slope-intercept form: solving for yy is the essential first step before the slope and y-intercept can be read off and used for graphing.
