Collinear points lie on the same line. Find the value of k for which the points (15,1), (-3,-8), and (3,k) are collinear. I don't understand this. Can someone please help?
It this a coordinate geometry problem???
if analytic geometry has to do with it than yes.
okay you could proceed as follows (refer the diagram)|dw:1365367371961:dw|
If they are collinear they will all lie on the same line then AB = AC+CB use the Distance Formula to calculate AB, AC and CB Substitute and solve for k
oh ok, that makes sense. I can do it now. Thank you so much!!!
