1. **State the problem:** Find the x- and y-intercepts of the line given by the equation $$3x - 4y = 12$$ and use them to sketch the line.
2. **Recall intercept definitions:**
- The x-intercept is where the line crosses the x-axis, so $y=0$.
- The y-intercept is where the line crosses the y-axis, so $x=0$.
3. **Find the x-intercept:**
Set $y=0$ in the equation:
$$3x - 4(0) = 12$$
$$3x = 12$$
Divide both sides by 3:
$$\cancel{3}x = \cancel{3}4$$
$$x = 4$$
So the x-intercept is at the point $(4,0)$.
4. **Find the y-intercept:**
Set $x=0$ in the equation:
$$3(0) - 4y = 12$$
$$-4y = 12$$
Divide both sides by $-4$:
$$\cancel{-4}y = \cancel{-4}(-3)$$
$$y = -3$$
So the y-intercept is at the point $(0,-3)$.
5. **Summary:**
- x-intercept: $(4,0)$
- y-intercept: $(0,-3)$
6. **Sketching the line:**
Plot the points $(4,0)$ and $(0,-3)$ on the coordinate plane and draw a straight line through them. This line represents the equation $3x - 4y = 12$.
This completes the solution.
