### Intersection of Lines and Plane Equation

Consider the lines \( \mathbf{r_1}(t) = \langle 2t - 3, t + 4, -t - 1 \rangle \) and \( \mathbf{r_2}(s) = \langle s + 6, s - 6, 3s + 6 \rangle \).

#### Part A:
**Objective:** Show that these two lines intersect and find the point of intersection.

#### Part B:
**Objective:** Find an equation for the plane that contains both lines.

**Explanation:**

1. **Intersection of Lines:**
   - Determine the values of the parameters \(t\) and \(s\) where the coordinates of \(\mathbf{r_1}(t)\) and \(\mathbf{r_2}(s)\) are equal.
   - Solve the resulting system of equations to find the point of intersection.

2. **Equation of the Plane:**
   - Once the point of intersection is identified, use the direction vectors of \(\mathbf{r_1}(t)\) and \(\mathbf{r_2}(s)\) to form the normal vector to the plane.
   - Use the point-normal form of the equation of the plane to derive its equation.

Please refer to relevant mathematical methods and algebraic tools to solve the above objectives.
