Question 01 (a) 

Find an equation of the plane that passes through the point with a normal vector . 
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! 
Hint 

Recall that any vector on a plane is perpendicular to the normal vector of the plane. 
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Solution

Please rate my easiness! It's quick and helps everyone guide their studies. If is some point on the plane, then it forms a vector with the given point on the plane . Since a normal vector on a plane is orthogonal to any vector lying on the plane, this vector is therefore perpendicular to the normal vector of the plane.
