1. **State the problem:** We need to graph the linear equation $$7y - 3 = -x$$.
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.
Start with the given equation:
$$7y - 3 = -x$$
Add 3 to both sides:
$$7y = -x + 3$$
Divide both sides by 7:
$$y = \frac{-x + 3}{7}$$
Show canceling step:
$$y = \frac{\cancel{7}(-x + 3)}{\cancel{7}}$$
Simplify:
$$y = -\frac{1}{7}x + \frac{3}{7}$$
3. **Identify slope and intercept:**
- Slope $m = -\frac{1}{7}$
- Y-intercept $b = \frac{3}{7}$
4. **Find x-intercept:** Set $y=0$ and solve for $x$:
$$0 = -\frac{1}{7}x + \frac{3}{7}$$
Multiply both sides by 7:
$$0 = -x + 3$$
Add $x$ to both sides:
$$x = 3$$
5. **Plot points:**
- Y-intercept at $(0, \frac{3}{7})$
- X-intercept at $(3, 0)$
6. **Draw the line:** Connect these two points with a straight line. The slope $-\frac{1}{7}$ means the line goes down 1 unit for every 7 units it moves to the right.
Final answer: The equation in slope-intercept form is $$y = -\frac{1}{7}x + \frac{3}{7}$$ which can be graphed using the intercepts $(0, \frac{3}{7})$ and $(3, 0)$.
