The equation of the straight line passing through the point (4, 3) and making intercepts on the co-ordinate axes whose sum is –1 is
As we learnt in
Intercept form of a straight line -
- wherein
and are the -intercept and -intercept respectively.
Let the equation of straight line be
i.e. ..........(1)
...........(2)
4(-1-a)+3a=a(-1-a)
-4 - a = - a - a2
and a+b=-1
if a=2, b=-3
a=-2, b=1
