Answer:
Total Number of lines will be 28
Step-by-step explanation:
We can use combinations to solve this question.
Let the two Collinear points be denoted by A and B and the other other points be denoted by x1,x2,x3,x4, x5 and x6.
Suppose that only A and B are collinear.
The number of lines determined by any two of x1 to x6 are given by 6C2= 15
The number of lines from A or B and x1---x6 is given by 6C1 * 2C1= 12
The number of lines from A to B is 1.
Total Number of lines = 15+ 12+ 1= 28
