I've been reviewing the things I know so far, and found this question
A line is drawn through (2,1), forming a right triangle at the 1st quadrant. Determine the centroid of the triangle with minimum area.
Now, if we have the point at (2,1), can the area decrease any further?
Isn't this the smaller area we can possibly obtain?
Why do 2+x and 1+y are necessary?
