Given : equation x-2y-6=0
To Find : which of the following ordered pairs is the solution of the equation x-2y-6=0
a.(2,4)
b.(0,3)
c.(-4,1)
d.(4,-1)
Solution:
ordered pair which is solution of the equation x-2y-6=0
will satisfy the equation
x-2y-6=0
a.(2,4)
substitute x = 2 and y = 4
=> LHS = 2 - 2(4) - 6
= 2 - 8 - 6
= -12
≠ RHS
b.(0,3)
substitute x =0 and y = 3
=> LHS = 0 - 2(3) - 6
= 0 - 6 - 6
= -12
≠ RHS
c.(-4,1)
substitute x = -4 and y = 1
=> LHS = -4 - 2(1) - 6
=-4 - 2 - 6
= -12
≠ RHS
d.(4,-1)
substitute x = 4 and y = -1
=> LHS = 4 - 2(-1) - 6
=4 +2 - 6
= 0
= RHS
Hence (4 , 1) is the required ordered pair
