Question

if (1,2),(1/2,3)and(0,K) are collinear points,then find value of K?

Answer 1

the answer of your question is "K = 4 .

here the collinear points means totalk value = 0

Answer 2

Let us assume that the points are A, B, C respectively and the ratio between AB and BC be m:1.
By applying section formula we can find out m as we know the x coordinate of C which is 0.
