Slope Formula
m = (y₂ - y₁) / (x₂ - x₁)
The slope measures the steepness and direction of a line. It is calculated by dividing the change in y-values (rise) by the change in x-values (run).
Example Calculation
Input: Point A (2, 3), Point B (6, 11)
Output: m = (11 - 3) / (6 - 2) = 8 / 4 = 2

Frequently Asked Questions
Verified answers to essential calculation and diagnostic questions.
Slope measures the steepness and direction of a line. It represents how much the y-value changes for every unit change in the x-value.
Slope is calculated by dividing the difference in y-coordinates by the difference in x-coordinates between two points.
A positive slope means the line rises from left to right.
A negative slope means the line falls from left to right.
A slope is undefined when the x-coordinates are equal, creating a vertical line.
The slopes of two perpendicular non-vertical lines are negative reciprocals of each other (m₁ · m₂ = -1), meaning one slope is the inverted negative value of the other.
