Answer:
The answer is B.
Step-by-step explanation:
the given eq. is 4x-3y=7
NOW...
Putting (1,-1) in the eq.
4(1)-3(-1)=7
4+3=7
7=7
Putting (3,4) in the eq.
4(3)-3(4)=7
12-12=7
0≠7
So option A is not correct
THEN,
Putting (1,-1) in the eq.
4(1)-3(-1)=7
4+3=7
7=7
Putting (4,3) in the eq.
4(4)-3(3)=7
16-9=7
7=7
So option B is correct
