Formula
Slope = change in y / change in x.
Points (1,2) and (5,10) have slope 2.
Enter the known values and apply Slope = change in y / change in x.. Keep signs, decimal places, and the order of operations consistent with the problem you are checking.
Use the Slope Calculator to solve or verify a math problem, compare inputs, and check a manual calculation.
Common math errors include using the wrong operation, dropping a negative sign, rounding intermediate steps too early, and confusing percentages with decimal values.
