Slope Calculator MY
Find the slope between two points, plus the line’s equation, y-intercept, length, angle and midpoint.
Point 1
Point 2
How it works
Enter the coordinates of two points. The calculator works out the slope (rise over run), the equation of the line, the y-intercept, the distance between the points, the angle of the line and the midpoint.

Frequently asked questions
How do I find the slope between two points?
Subtract the y-values and divide by the difference in x-values: (y₂ − y₁) ÷ (x₂ − x₁). For (1,2) and (4,8) the slope is 2.
What is the slope formula?
Slope = rise over run = (y₂ − y₁) ÷ (x₂ − x₁), the change in y divided by the change in x.
What is a zero slope?
A zero slope is a horizontal line — there is no rise, so the line is flat.
What is an undefined slope?
A vertical line has an undefined slope, because the run (change in x) is zero and you cannot divide by zero.
What does rise over run mean?
Rise is the vertical change between two points and run is the horizontal change; slope is rise divided by run.
What is slope-intercept form?
It is y = mx + b, where m is the slope and b is the point where the line crosses the y-axis.
Slope Calculator
Slope measures how steep a line is — how much it rises or falls for each step across. This calculator finds the slope between two points.
The slope formula
Slope (m) = rise ÷ run = (y₂ − y₁) ÷ (x₂ − x₁). For the points (1, 2) and (4, 8): (8 − 2) ÷ (4 − 1) = 6 ÷ 3 = 2.
What the sign means
- Positive slope rises left to right.
- Negative slope falls left to right.
- Zero slope is a flat, horizontal line.
- Undefined slope is a vertical line (the run is zero, so you cannot divide).
Slope-intercept form
A line is often written y = mx + b, where m is the slope and b is the y-intercept (where the line crosses the y-axis).
