How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Slope (m) = (y₂−y₁)/(x₂−x₁). Line equation: y = mx + b, where b = y₁ − m×x₁. A positive slope goes up left-to-right; negative goes down. Horizontal lines have slope 0; vertical lines have undefined slope.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

What does slope mean?

Slope represents the rate of change: how much y changes per unit increase in x. A slope of 2 means for every 1 unit right, the line goes 2 units up.
