Points `P(a, -4), Q (-2, b)` and `R(0, 2)` are collinear, such that `PR = 2 QR`. Calculate the values of `a` and` b`.

Points P (a, -4), Q (-2, b) and R (0, 2) are collinear. If lies between P and R, such that PR = 2QR, calculate the values of a and b.

If P(5,7), Q(x,-2) and R(-3,y) are collinear points such that PR = 2PQ, calculate the values of x and y.

If the points P(-3,9) ,Q(a , b) and R(4 , - 5) are collinear and a + b=1, then find the values of a and b.

If the points P (a, 1), Q (1, b), R (-2, 11) are collinear and Q be the mid - point of bar(PR) , then find the value of a and b.

If the points P(-3,\ 9),\ \ Q(a ,\ b) and R(4,\ -5) are collinear and a+b=1 , find the values of a and b .

If the points P(-3,9),Q(a,b) and R(4,-5) are collinear and a+b=1, find the values of a and b

If the points P (0,3,2), Q(1,2,-2) and R (4,-1,t) are collinear, find the value of t.
