If three points (h, 0), (a, b) and (o, k...

If three points (h, 0), (a, b) and (o, k) lie on a line, show that `a/h+b/k=1`.

Text Solution

Verified by Experts

Since the lines A(h,0),B(a,b) and C(0,k) lie on the same line.
Slope of AB=Slope of BC
`(b-0) div ( a-h)` =`(k-b) div (0-a)`
It gives, hk=ak+hb
