Question 741263: show that the pionts A(1,-1), B(4,-2) and C(16,1) are collinear

if the points A(,), B(,) and C(,) are collinear, they will lie in a straight line;
in order to prove the points to lie on a line, as there exists a line containing three points and every line has a slope}}}
Hence it will be sufficient to prove that the slope calculated taking points at a time should be equal.
Slope of line taking points (x1,y1)= (,) and (x2,y2)=(,) is
Slope of line taking points (x1,y1)= (,) and (x2,y2)=(,) is
since , given points are NOT collinear
