1. **Problem:** Find the slope of the tangent line to $f(x) = 3x^2 - 2x$ at the point $(-1,5)$ and then find the equation of the tangent line in the form $y = mx + b$.
2. **Formula:** The slope of the tangent line at a point is given by the derivative $f'(x)$ evaluated at that point.
3. **Find the derivative:**
$$f'(x) = \frac{d}{dx}(3x^2 - 2x) = 6x - 2$$
4. **Evaluate the slope at $x = -1$:**
$$m = f'(-1) = 6(-1) - 2 = -6 - 2 = -8$$
5. **Use point-slope form to find the equation:**
The point-slope form is:
$$y - y_1 = m(x - x_1)$$
Substitute $m = -8$, $x_1 = -1$, and $y_1 = 5$:
$$y - 5 = -8(x + 1)$$
6. **Simplify the equation:**
$$y - 5 = -8x - 8$$
$$y = -8x - 8 + 5$$
$$y = -8x - 3$$
**Final answer:** The slope of the tangent line is $-8$ and the equation of the tangent line is $$y = -8x - 3$$.
