# Standard Vector form equation of the plane

**Question**

- What is the cartesion equation of a plane with vector equation equation to r.(3i + j – 2k) = 5
- Determine the distance from the plane from origin for equation 3x + y – 2k = 51

**Answer**

- 3x + y – 2k = 5
- 51/√14

*Note:*

*Cartesian equation of the plane*

*Ax+By+Cz = D*

*Standard vector form equation of the plane*

*r.n = D*
