Standard Form Calculator

Convert a linear equation between slope-intercept form (y = mx + b) and standard form (Ax + By = C) — with the slope, intercepts, and full step-by-step working.

Standard form:  Ax + By = C  ·  Slope-intercept:  y = mx + b
y = slope m x + y-intercept b

Choose the form you have, then enter its values. Decimals and negatives are fine. The tool returns the other form plus the slope and intercepts.
