Finding the equation of a line can feel like solving a puzzle! If you have two points, you can use the formula (y = mx + b), where "m" is the slope and "b" is the y-intercept. Calculate the slope with ((y_2 - y_1)/(x_2 - x_1)), and then use one point to solve for "b". If you have the slope and a point, plug them in to find the line's equation. Are you working on a specific problem, or just exploring how this works?
