If these points are known (x1,y1), (x2,y2) and you also know y of third point and you are going to find x of third point do this in main:
Solve((x-x1)/(x1-x2)=(y-y1)/(y1-y2),x)

what you said is doing it using Line Equation ...
if there were more than two points which were not aligned in a line, then what should we do ?

You are right.
I don't remember exactly but in Static App you can enter your Xs and Ys then find a linear regression and solving it for unknown x or y.
