1. We are given two points: $(5,2)$ and $(-2,-12)$.
2. The goal is to find the equation of the line passing through these points in standard form and general form.
3. First, calculate the slope $m$ using the formula:
$$m=\frac{y_2 - y_1}{x_2 - x_1} = \frac{-12 - 2}{-2 - 5} = \frac{-14}{-7} = 2$$
4. Use point-slope form with point $(5,2)$:
$$y - y_1 = m(x - x_1)$$
$$y - 2 = 2(x - 5)$$
5. Simplify:
$$y - 2 = 2x - 10$$
$$y = 2x - 8$$
6. To write in standard form $Ax + By = C$, rearrange:
$$y = 2x - 8$$
$$-2x + y = -8$$
7. Multiply both sides by $-1$ to make $A$ positive:
$$\cancel{-1}(-2x + y) = \cancel{-1}(-8)$$
$$2x - y = 8$$
8. The general form is the same as standard form here:
$$2x - y - 8 = 0$$
Final answers:
- Standard form: $2x - y = 8$
- General form: $2x - y - 8 = 0$
