Let the equation of the line be

x

a

+

y

b

=1...(i)
which passes through (4, 3).
∴

4

a

+

3

b

=1...(ii)
It is given that a + b = - 1 ...(iii)
On solving Eqs. (i) and (ii), we get
a = -2 , b = 1 or a = 2, b = - 3
On substituting the values of a and b in Eq. (i), we get

x

−2

+

y

1

=1 and

x

2

+

y

−3

=1
