Question

1
The equation of a line passing through (a, b) and
parallel to the line xla + y/b = 1 is -
(A) Xa+ y/b = 0 (B) x/a + y/b = 2
(C) x/a + y/b = 3 (D) x/a + y/b + 2 = 0​

Answer 1

option (B)

if we put

x = a and y = b

then we see that only option (B) is satisfied.

proof :

put the value of x and y in option (B)

now

=> a/a + b/b

= 1 + 1

=> 2 = R.H.S

so

L.H.S. = R.H.S.

Hope it may Help you.
