About Slope Calculator (Formula)
The slope calculator calculates the slope of a line based on the given inputs. The formula used to calculate the slope depends on the scenario.
- If two points (x1, y1) and (x2, y2) are known, the slope (m) is calculated using the following formula:
m = (y2 – y1) / (x2 – x1)
This formula calculates the change in the y-coordinates divided by the change in the x-coordinates between the two points.
- If one point (x1, y1) and the slope (m) are known, the formula to calculate the slope is simply the given slope value:
m = slope
In this case, you already know the slope, so no calculation is needed.
The slope represents the steepness and direction of a line. A positive slope indicates an upward direction, a negative slope indicates a downward direction, and a slope of zero indicates a horizontal line.
