Short Answer

Expert verified

The graph of the equation is

Step by step solution

Step 1. Given Information

Given equation is $3 x - 4 y = 12$

The graph of the equation is to be determined using the intercepts.

Step 2. Find the x-intercept

To determine the x-intercept, plugging $y = 0$ in the equation and solving for x:

$3 x - 4 y = 12 3 x - 4 (0) = 12 3 x - 0 = 12 3 x = 12 \frac{3 x}{3} = \frac{12}{3} x = 4$

So the x-intercept is $(4, 0)$

Step 3. Find the y-intercept

To determine the y-intercept, plugging $x = 0$ in the equation and solving for y:

$3 x - 4 y = 12 3 (0) - 4 y = 12 0 - 4 y = 12 - 4 y = 12 \frac{- 4 y}{- 4} = \frac{12}{- 4} y = - 3$

So the y-intercept is $(0, - 3)$

Step 4. Plotting the intercepts

Plotting the intercepts on the coordinate plane and joining them using a line:

Step 5. Conclusion

The graph of the equation using the intercepts is
