1. **State the problem:** Rewrite the equation $$\frac{1}{2}x - \frac{3}{4}y = \frac{5}{6}$$ in the form $$y = mx + c$$ and find the gradient $$m$$.
2. **Formula and rules:** The slope-intercept form of a line is $$y = mx + c$$ where $$m$$ is the gradient (slope) and $$c$$ is the y-intercept.
3. **Isolate $$y$$:** Start with the given equation:
$$\frac{1}{2}x - \frac{3}{4}y = \frac{5}{6}$$
Subtract $$\frac{1}{2}x$$ from both sides:
$$- \frac{3}{4}y = - \frac{1}{2}x + \frac{5}{6}$$
4. **Solve for $$y$$:** Multiply both sides by $$-\frac{4}{3}$$ to isolate $$y$$:
$$y = \left(- \frac{4}{3}\right) \left(- \frac{1}{2}x + \frac{5}{6}\right)$$
5. **Distribute:**
$$y = \left(- \frac{4}{3}\right) \left(- \frac{1}{2}x\right) + \left(- \frac{4}{3}\right) \left(\frac{5}{6}\right)$$
6. **Simplify each term:**
$$y = \frac{4}{3} \times \frac{1}{2} x - \frac{4}{3} \times \frac{5}{6}$$
$$y = \frac{4}{6}x - \frac{20}{18}$$
7. **Reduce fractions:**
$$\frac{4}{6} = \frac{2}{3}$$ and $$\frac{20}{18} = \frac{10}{9}$$
8. **Final equation:**
$$y = \frac{2}{3}x - \frac{10}{9}$$
9. **Gradient:** The gradient $$m$$ is the coefficient of $$x$$, which is $$\frac{2}{3}$$.
**Answer:** The equation in slope-intercept form is $$y = \frac{2}{3}x - \frac{10}{9}$$ and the gradient $$m = \frac{2}{3}$$.
