Graph Inequality 169298
1. **State the problem:** Graph the inequality $3x - 4y > 12$ using intercepts.
2. **Rewrite the inequality as an equation to find intercepts:**
$$3x - 4y = 12$$
3. **Find the x-intercept:** Set $y=0$ and solve for $x$.
$$3x - 4(0) = 12 \implies 3x = 12 \implies x = 4$$
So the x-intercept is $(4,0)$.
4. **Find the y-intercept:** Set $x=0$ and solve for $y$.
$$3(0) - 4y = 12 \implies -4y = 12 \implies y = -3$$
So the y-intercept is $(0,-3)$.
5. **Plot the intercepts:** Plot points $(4,0)$ and $(0,-3)$ on the coordinate plane.
6. **Draw the boundary line:** Draw the line through these points. Since the inequality is strict ($>$), the line is dashed.
7. **Determine which side to shade:** Pick a test point not on the line, e.g., $(0,0)$.
Substitute into the inequality:
$$3(0) - 4(0) > 12 \implies 0 > 12$$
This is false, so shade the side opposite to $(0,0)$.
**Final answer:** The graph is the region above the dashed line through $(4,0)$ and $(0,-3)$.
