Question

Given aside are four points P,Q,R &
s. check which three of them are
collinear & which three are
non
collinear. In the case of three collinear
points, state which of them is
between the other two.
​

Answer 1

divide into two parts as PQR and QRS and find is it collinear or not?

if PQR is collinear,

find the slope of PQ and Slope of QR

if the slope of PQ and slope of QR is equal, Q is the mid point because Q lies on both the lines of PQ and QR.
