Question

How many line are determined by three distinct points​

Answer 1

Answer:

three

Step-by-step explanation:

If the given points in the plane are co-llinear then only one possibility of 1 line can be drawn.

If the given points in the plane are not co-llinear, we can determine the lines from the below given steps,

To draw a line, we need atleast two points.

So,Choosing two points from the given Three points:  

3 ^ C  2 =  3!  /2!×1!   =3 (The 3 in the power represents the given three points and the 2 in the power represents the chosen two points)

∴, the number of lines that could be drawn =  3^ C 2  =  3! /  2!×1!   =3
