Answer:
Step-by-step explanation:
Let the intercepts made on X and Y axes are 'a' and 'b' respectively.
Also, their ratio is 5:3
Therefore, we will get,
Now, we know that, equation of line having intercepts 'a' and 'b' on X and Y axes respectively is given by,
Also, the given line passes through (-4, 3).
Therefore, it will satisfy this equation (ii).
Therefore,substiting the values in (ii), we get,
Now, substituting the value of a from eqn (i), we get,
Therefore, we will get,
Now, substituting the value of 'a' and 'b' in eqn (ii), we will get the desired equation, i.e.,
Hence, the correct option is (b) 3x + 5y = 3

Answer:
m:n=2:5
(x1,y1)=(4,3)
nx+my=nx1+my1
3x+5y=3*(-4)+5*(3)
3x+5y=-12+15
3x+5y=3
3x+5y-3=0
