Math calculator
Slope Calculator
Find slope, rise, run, and line angle from two coordinate points.
Formula
Slope formula
slope = (y2 - y1) / (x2 - x1)
Points (1,2) and (5,10) have slope 2.
FAQs
What if x1 and x2 are the same?+
The line is vertical, so slope is undefined.
What does negative slope mean?+
The line falls as x increases.
How does the Slope Calculator calculate the result?+
It uses the Slope formula: slope = (y2 - y1) / (x2 - x1). Points (1,2) and (5,10) have slope 2.
What information do I need to use the Slope Calculator?+
Find slope, rise, run, and line angle from two coordinate points.
How accurate is the Slope Calculator?+
Slope Calculator applies the formula and assumptions shown on this page. Results may be rounded for readability, so verify changing rates, thresholds, medical guidance, or legal rules with the cited source or a qualified professional.
What should I check before using the Slope Calculator result?+
Check that the units, dates, rates, and assumptions match your situation. Change one input at a time to understand which values have the largest effect on the result.
