Step-by-step explanation:
Now we have to check the equation, which satisfied by the point (4,1).
(a) x + 2y = 5
LHS = x + 2y = 5
= 4 + 2(1) = 5
= 4 + 2 = 5
=
6
≠
5
=
L
H
S
≠
R
H
S
(b) x + 2y = 6
LHS = x + 2y = 6
= 4 + 2(1) = 6
= 4 + 2 = 6
= 6 = 6
=LHS = RHS
(c) x + 2y = 16
LHS = x + 2y = 16
= 4 + 2(1) = 16
= 4 + 2 = 16
=
6
≠
16
=
L
H
S
≠
R
H

(d) x + 2y = -6
LHS = x + 2y = -6
= 4 + 2(1) = -6
= 4 + 2 = -6
=
6
≠
−
6
=
L
H

Therefore, option (b) x + 2y = 6 is the correct option.
