Line through two points
Find slope, y-intercept and standard form Ax + By = C, including vertical lines.
Enter two different Cartesian points. The tool computes the rise-over-run slope when defined, the y-intercept and a standard-form coefficient set that also represents vertical lines.
How to use
- Enter your text, values, or image.
- Adjust the options and run the tool.
- Copy or download your result.
Worked example
Example input
First x: 1 First y: 3 Second x: 2 Second y: 5
Example result
{
"slope": 2,
"intercept": 1,
"A": 2,
"B": -1,
"C": -1
}Limitations and details
Coincident points are rejected; vertical lines return null slope and intercept, and standard-form coefficients are not normalized.
