Slope Calculator

Find the slope between two points.

Slope (m) 2

Angle (°) 63.435

Formula: m = (y₂ − y₁) ÷ (x₂ − x₁)

Step-by-step with your numbers:

1. Values used:

2. x₁ = 1

3. y₁ = 2

4. x₂ = 4

5. y₂ = 8

7. Slope (m) = x₁ x y₁ = 1 x 2 = 2

8. Angle = 63.435°

Did we solve your problem today?

The steepness of a line between two points.

The math behind it

slope = rise ÷ run = (y₂ − y₁) ÷ (x₂ − x₁).

(1,2) to (4,8) → slope 2.

Vertical line?

Undefined slope — the run is zero.
