1.	a) 5
Answer» Solution: We have given that point let A(1,2) and point B(3,4) and the equation is 3x-4y+a = 0 putting both values of A and B in LHS of equation, we get 31-42+a = 0 --------(1) a = 5 33-44+a = 0 ------------(2) a = 7 From both equation we get the values of a a =5 and a= 7 So the correct answer is (b)

Answer»

Solution:

We have given that point let A(1,2) and point B(3,4) and

the equation is 3x-4y+a = 0

putting both values of A and B in LHS of equation, we get

3*1-4*2+a = 0 --------(1)

a = 5

3*3-4*4+a = 0 ------------(2)

a = 7

From both equation we get the values of a

a =5 and a= 7

So the correct answer is (b)
