Slope Calculator
Calculate the slope of a line from two points.
About this Tool
The Slope Calculator determines the slope or gradient of a line connecting two points in a 2D Cartesian coordinate system. The slope represents the steepness of the line, often described as 'rise over run.' The calculator also provides the equation of the line in slope-intercept form (y = mx + b).
Common Use Cases
Algebra and Geometry
Quickly solve for the slope in math homework and understand the relationship between points on a line.
Physics
Calculate rates of change, such as velocity from a position-time graph.
Engineering and Construction
Determine the grade or incline of a road, ramp, or piece of land.
Pro Tips
- !
Positive vs. Negative Slope
A positive slope means the line goes up from left to right. A negative slope means it goes down.
- !
Zero Slope
A slope of zero indicates a perfectly horizontal line.
- !
Undefined Slope
An 'undefined' slope indicates a perfectly vertical line, as the 'run' (change in x) is zero.
