Let us consider the plane **3x+2y+z-6=0**. Let **A** be the point at which this plane intersects the axis **Ox**, that is, **A(2;0;0)**. The point **B(0;3;0)** is the point at which the plane intersects the axis **Oy**, the point **C(0;0;6)** is the point at which the plane intersects the axis **Oz**. The equation **x/a+y/b+z/c=1** is called the **intercept form of the equation of a plane**.

The plane intersects the axes **Ox**, **Oy**, **Oz** respectively at the points **A(a;0;0)**, **B(0;b;0)**, **C(0;0;c)**.

The intercept form of the equation of the plane that is shown is: **x/2+y/3+z/6=1**.
