1. Write the equation of a line in slope-intercept form containing these two points: \((-6, 3)\) and \( (2, -1)\).

**Explanation**: 

To write the equation of a line in slope-intercept form \(y = mx + b\), you need to determine the slope \(m\) and the y-intercept \(b\).

**Steps**:
1. **Calculate the slope (m)**: Use the formula
   \[
   m = \frac{y_2 - y_1}{x_2 - x_1}
   \]
   Plug in the points: \( (-6, 3) \) and \( (2, -1) \).

2. **Find the y-intercept (b)**: Use one of the points and the found slope in the slope-intercept equation to solve for \(b\).

3. **Write the final equation**: Substitute the values of \(m\) and \(b\) into \(y = mx + b\).
