## Quick Answer

Find the linear equation y = mx + b for any straight line. Enter a slope and intercept, two coordinate points, or a point and slope.

## Definition

A y = mx + b calculator solves linear equations to determine the slope-intercept form of a straight line. By providing either the slope and y-intercept, two distinct coordinates, or one coordinate and the slope, the calculator outputs the slope (m), y-intercept (b), standard equation form, and lets you query coordinates on the line.

## How to Use

1. **Select input case** — Choose either Slope-Intercept, Two Points, or Point-Slope mode depending on your known parameters.
2. **Enter line details** — Type the numerical values for your slope, y-intercept, or coordinates.
3. **Read the equation** — View the slope-intercept equation, graph coordinate plane, points table, and query interface.
