How do you find the slope of the line that passes through 2 points?

Assume your points are (x1, y1) and (x2, y2). The slope of a line is its rise (the change in y-coordinates) over its run (the change in x-coordinates).

So to find the slope of the line, you substitute the correct values into the formula (y2 - y1) / (x2 - x1).
