Question

if A , B and C are collinear then what is relation between them
​

Answer 1

Step-by-step explanation:

given point (1,2)(0,0)(a,b)

these points r collinear it means their slopes r equal

now slope m AB = y2-y1/x2-x1=0-2/0-1

= -2/-1=2

& slope BC= b-0/a-0

= b/a

now 2= b/a

b=2a

this is the relation b/w a and b....
