Determine if the point (1,5),(2,3)and (-2,-11) are collinear.

1.	Determine if the point (1,5),(2,3)and (-2,-11) are collinear.
Answer» orUsing the Distance Formula ,\xa01st and 2nd distance ,=>\xa0=>\xa0=>2nd and 3rd ,=>=>=>1st and 3rd point .=>=>=>so ,Ist and 2nd + 2nd and 3rd = 1st and 3rd is law of collinearity ,Lets check ,5+ 212 = 256217 not equal 256\xa0Hence ,It does not satisfy the condition , Hence they are not collinear .
