Parallel Line 67Dff3
1. The problem asks us to find the equation of a line parallel to the line $y = -\frac{1}{3}x + 1$ that passes through the point $(1, -2)$.
2. Recall that parallel lines have the same slope. The slope of the given line is $m = -\frac{1}{3}$.
3. Use the point-slope form of a line equation: $$y - y_1 = m(x - x_1)$$ where $(x_1, y_1)$ is the point the line passes through and $m$ is the slope.
4. Substitute $m = -\frac{1}{3}$ and the point $(1, -2)$:
$$y - (-2) = -\frac{1}{3}(x - 1)$$
5. Simplify the equation:
$$y + 2 = -\frac{1}{3}x + \frac{1}{3}$$
6. Subtract 2 from both sides to solve for $y$:
$$y = -\frac{1}{3}x + \frac{1}{3} - 2$$
7. Convert $2$ to thirds to combine:
$$2 = \frac{6}{3}$$
8. So,
$$y = -\frac{1}{3}x + \frac{1}{3} - \frac{6}{3} = -\frac{1}{3}x - \frac{5}{3}$$
**Final answer:**
$$y = -\frac{1}{3}x - \frac{5}{3}$$
