1. The problem is to find the equation of a line given certain conditions (e.g., points or slope). 2. The general formula for the equation of a line is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept. 3. If two points $(x_1, y_1)$ and $(x_2, y_2)$ are given, the slope $m$ is calculated by: $$m = \frac{y_2 - y_1}{x_2 - x_1}$$ 4. After finding $m$, use one point to solve for $b$ by substituting into $y = mx + b$: $$b = y_1 - m x_1$$ 5. Substitute $m$ and $b$ back into the equation $y = mx + b$ to get the final equation of the line. 6. If the problem provides slope and a point, directly substitute into the point-slope form: $$y - y_1 = m(x - x_1)$$ 7. Simplify the equation to slope-intercept form if needed. This method applies to all line equation problems.
