If 3 points are collinear the solve for t (3,3) (t,1) (8,6)

Let A(3,3), B(t,1), C(8,6) be the three points.
If they are collinear, the slope of line AB would be the same as the slope of line BC.
The slope m of a line between two points is given by
m = (y2y1)/(x2x1)
Equate mAB and mBC in terms of t.
Solve for t.
