1. **State the problem:** We need to graph the linear equation $$-\frac{1}{2}x + y = \frac{3}{4}$$ in two variables $x$ and $y$.
2. **Rewrite the equation in slope-intercept form:** The slope-intercept form is $$y = mx + b$$ where $m$ is the slope and $b$ is the $y$-intercept.
Starting with the given equation:
$$-\frac{1}{2}x + y = \frac{3}{4}$$
Add $\frac{1}{2}x$ to both sides:
$$y = \frac{1}{2}x + \frac{3}{4}$$
3. **Identify slope and intercept:**
- Slope $m = \frac{1}{2}$
- $y$-intercept $b = \frac{3}{4}$
4. **Find the $x$-intercept:** Set $y=0$ and solve for $x$:
$$0 = \frac{1}{2}x + \frac{3}{4}$$
Subtract $\frac{3}{4}$:
$$-\frac{3}{4} = \frac{1}{2}x$$
Multiply both sides by 2:
$$2 \times -\frac{3}{4} = \cancel{2} \times \frac{1}{\cancel{2}} x$$
$$-\frac{6}{4} = x$$
Simplify:
$$x = -\frac{3}{2}$$
5. **Summary:**
- $y$-intercept at $(0, \frac{3}{4})$
- $x$-intercept at $(-\frac{3}{2}, 0)$
- Slope $\frac{1}{2}$ means the line rises 1 unit for every 2 units it moves right.
6. **Final equation for graphing:**
$$y = \frac{1}{2}x + \frac{3}{4}$$
This is the equation to plot the line with the intercepts and slope described above.
