Slope Formula

Front

What is the slope formula?

Back

The slope formula is given by m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on a line.

How do you find the slope of a line given two points?

Back

To find the slope, subtract the y-coordinates and divide by the difference of the x-coordinates: m = (y2 - y1) / (x2 - x1).
