# Math Help - Vector Help Needed

1. ## Vector Help Needed

Hi

I have a plane with the equation

21814x + (-20063y) + 698z = -1941121897

I have a point located at xyz coordinates 1003811,998176,100803.
How do i calculate the xyz coordinates of a point located in a direction normal to the plane above, at a distance of 100 units from the point above?

2. Can you identify wich vector is $(21841,20063,698)$ and what special property does it have?
