Seven calculations you can do with two coordinates, in one tool. Choose one under "Calculation" and enter the points.
What You Can Do
- Line equation
- The line through both points as y = mx + b, or x = c for a vertical line.
- Distance, midpoint, slope
- The distance between the points, the point halfway, and Δy/Δx.
- Point-slope form
- Writes the line from one point and a slope.
- 3D distance and midpoint
- Adds z coordinates for points in space.
How to Use Two Points: Distance, Midpoint, Slope, Line
- 1Choose a calculationPick what you need. 3D calculations show extra z fields.
- 2Enter coordinatesType (x1, y1) and (x2, y2). Negatives and decimals work.
- 3Read the resultYou get an equation or coordinates.
Examples
Line through (1, 2) and (3, 6)
Input: (1, 2), (3, 6)
Result: y = 2x + 0
Distance from the origin to (3, 4)
Input: (0, 0), (3, 4)
Result: 5
Midpoint of (2, 4) and (8, 10)
Input: (2, 4), (8, 10)
Result: (5, 7)
Common Use Cases
- Checking coordinate geometry homework
- Straight-line distance between map or drawing coordinates
- The slope of a trend line
Frequently Asked Questions (FAQ)
What if x1 equals x2?
The line is vertical and has no slope. The equation is given as x = 2, for example, and the slope as "vertical".
What unit is the distance?
The same as the coordinates. Coordinates in meters give meters.
