(x/a) + (y/b) = 1 be the equation of line
(4/a) + (3/b) = 1
also a+b = -1
two equation two variables
you can solve from here revert if problem still persists
(4/a) + (3/b) = 1
also a+b = -1

Dear student
Let yhe kine is
x/a + y/b = 1
Now we are given that a+ b = – 1
&
4/a + 3/b = 1
4b + 3 (- 1 – b) = (-1 – b) b
it is quadratic in b
Now you can find b then a
hence you can also find the equation of line.
