Question

Find a relation between x and y if the point a(2,1)b(x,y)and c(7,5)are collinear.

Answer 1

sry if its wrong....

Answer 2

Answer:

firstly,

the point is a A(2,1),B(X,Y),C(7,5) are collinear

so,

we find the value by the help of distance formula

distance formula = root (x2-X1)^2+(y2-y1)^2

Step-by-step explaination

firstly we find out the AB=root(X-2)^2+(y-1)^2

underroot X^2-4x+4+y^2-2y+1

underroot X^2-4x+y^2-2y+5
