1. **State the problem:** We need to graph the line given by the equation $$y - 4 = -\frac{2}{3}(x - 1)$$ which is in point-slope form.
2. **Recall the formula:** The point-slope form of a line is $$y - y_1 = m(x - x_1)$$ where $m$ is the slope and $(x_1,y_1)$ is a point on the line.
3. **Identify slope and point:** Here, $m = -\frac{2}{3}$ and the point is $(1,4)$.
4. **Convert to slope-intercept form:**
$$y - 4 = -\frac{2}{3}(x - 1)$$
$$y - 4 = -\frac{2}{3}x + \frac{2}{3}$$
$$y = -\frac{2}{3}x + \frac{2}{3} + 4$$
$$y = -\frac{2}{3}x + \frac{2}{3} + \frac{12}{3}$$
$$y = -\frac{2}{3}x + \frac{14}{3}$$
5. **Find intercepts:**
- **y-intercept:** Set $x=0$:
$$y = -\frac{2}{3}(0) + \frac{14}{3} = \frac{14}{3} \approx 4.67$$
- **x-intercept:** Set $y=0$:
$$0 = -\frac{2}{3}x + \frac{14}{3}$$
Multiply both sides by 3:
$$0 = -2x + 14$$
Add $2x$ to both sides:
$$2x = 14$$
Divide both sides by 2:
$$x = \cancel{\frac{14}{2}} = 7$$
6. **Plot points:** The line passes through $(1,4)$, $(0, \frac{14}{3})$, and $(7,0)$.
7. **Draw the line:** Connect these points with a straight line extending in both directions.
**Final answer:** The line has slope $-\frac{2}{3}$ and y-intercept $\frac{14}{3}$. It passes through $(1,4)$ and $(7,0)$.
