Sure, I can convert the solutions into step-by-step solutions with LaTeX tags intact. Here's an example: Original solution: The equation of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by: $y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$ Step-by-step solution: To find the equation of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$: 1. Use the point-slope form of a line: $y-y_1=m(x-x_1)$ where $m$ is the slope of the line. 2. Find the slope of the line using the two points: $m=\frac{y_2-y_1}{x_2-x_1}$ 3. Substitute the slope and one of the points into the point-slope form: $y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$ This is the equation of the line passing through $(x_1,y_1)$ and $(x_2,y_2)$.
