This Plane Intercept Form (3D) Calculator helps you write a plane in intercept form in three-dimensional space. Start with either a standard plane equation or the x-, y-, and z-intercepts, then rewrite the equation in the form x/a + y/b + z/c = 1. This makes it easier to see where the plane meets each axis. It is a simple way to check answers, understand the method clearly, and practise 3D coordinate geometry step by step.

Step-by-step method

  1. Put the plane into standard form Ax + By + Cz = d.
  2. Compute the intercepts a = d/A, b = d/B, c = d/C.
  3. Write intercept form x/a + y/b + z/c = 1.

Formula:

\(\frac{x}{a} + \frac{y}{b} + \frac{z}{c} = 1\)
