Slope Formula

m = (y₂ − y₁) ÷ (x₂ − x₁) = rise ÷ run

Positive slope rises to the right, negative falls, zero is flat, and a vertical line has an undefined slope. As a percent grade, slope × 100.

Tips

Fractions work in the boxes (1/2). The graph marks both points and the midpoint (hollow circle); the dashed lines show the run and rise.
