What is the standard form of the equation of a plane?

The standard form of the equation of a plane is Ax+By+Cz=DA x plus B y plus C z equals D, where A,B,C,and D are real numbers not all equal to zero.

The intercepts of a plane are the points where the plane crosses each axis. To determine an intercept, let the values of the other variables equal zero. For example, to find the x-intercept of a plane, let y=0 and z=0.

Intercepts may be used to graph planes and to write equations of planes from graphs.

Planes may have one, two, or three intercepts.
