Question 494712: Please help me
How many distinct segments can be drawn between: 6 points.
Without drawing, predict how many segments can be drawn between 7, 8, and 9? Describe how you made your prediction.
Generalize your prediction by writing an algebraic expression that represents how many segments can be drawn between n points, no three of which collinear.

You can put this solution on YOUR website! How many distinct segments can be drawn between: 6 points.
Answer if no 3 are collinear = 6C2 = (6*5)/(1*2) = 15

Without drawing, predict how many segments can be drawn between 7, 8, and 9?
If no 3 are collinear:
7C2 = 21
8C2 = 28
9C2 = 36
