How To Find Slope?

To find the slope of a line, use the formula:

Slope = Rise / Run

Rise is the vertical change between any two points on the line. Run is the horizontal change between the same two points.

To calculate:

  • Pick any two points (x1, y1) and (x2, y2) on the line
  • Rise is the difference in the y-coordinates: y2 - y1
  • Run is the difference in the x-coordinates: x2 - x1
  • Plug the differences into the slope formula: Slope = (y2 - y1) / (x2 - x1)

Make sure to use corresponding points - the points must have the same x-value for the rise and the same y-value for the run. The slope will tell you the "steepness" and direction of the line.
