Find Slope
The slope measures vertical change divided by horizontal change. A zero denominator means the line is vertical.
Formula: m = (y₂−y₁) ÷ (x₂−x₁)
Keep angles, lengths, masses, and rates in the convention expected by the calculator. A unit conversion should happen before the main formula, not after a mixed-unit calculation.
If you know a standard case, use it as a reference to confirm the calculator output.
