Question

If the point (1,1) lies on the line passing
through the points (a,0) and (0,b), then
1/a+1/b=?​

Answer 1

Step-by-step explanation:

Given  

If the point (1,1) lies on the line passing through the points (a,0) and (0,b), then1/a+1/b=?

We need to find area of triangle which is equal to zero.

Therefore area of triangle = 1/2 (a(b – 1) + 0 + 1 (0 – b)

So ab – a – b = 0

So a + b = ab

So a/ab + b/ab = ab/ab (dividing both sides by ab)

So 1/b + 1/a = 1

Therefore 1/a + 1/b = 1
