Formula and methodology
Formula: y−y₁=m(x−x₁); y-intercept b=y₁−mx₁.
Point-slope form keeps the supplied point visible while the intercept form gives a direct equation for graphing.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Point x — minimum -1000000000000; maximum 1000000000000
- Point y — minimum -1000000000000; maximum 1000000000000
- Slope m — minimum -1000000000000; maximum 1000000000000
Worked example
| Input | Value |
|---|---|
| Point x | 3 |
| Point y | 5 |
| Slope m | 2 |
y=2x−1; y-intercept =−1.
Assumptions and limits
- The relation is a nonvertical line with a finite slope.
- Coordinates use a common Cartesian scale.
- Rounding is applied only to display, not to the calculation.
