Question
How many least number of distinct points determine a unique line?
✓
Answer
If we have a single point A then we can draw infinite number of lines through it, while if we have two points A and B; Then only one unique line passes through both of them. When we have one point, 
Therefore, a minimum of two distinct are required to determine a unique line.
Therefore, a minimum of two distinct are required to determine a unique line.Need a full question paper?
