What Does Rise Over Run Mean?

Rise over run is another way to describe slope. The rise is the vertical change between two points, and the run is the horizontal change.

How To Calculate Slope

  1. Enter two points.
  2. Subtract the y-values to get the rise.
  3. Subtract the x-values to get the run.
  4. Divide rise by run to get slope.
slope = (y2 - y1) / (x2 - x1)

Worked Example

For points (0, 0) and (4, 2), the slope is 0.5.

rise = 2
run = 4
slope = 2 / 4 = 0.5

Frequently Asked Questions

What if the run is 0?

The slope is undefined because the line is vertical.

Can slope be negative?

Yes. If the line goes down as x increases, the slope is negative.

Does the angle help?

Yes. It shows the line direction in degrees relative to the x-axis.

Can I use decimal coordinates?

Yes. Decimal coordinates are supported.
