Answer:
B.
Step-by-step explanation:
we know that
If a ordered pair is a solution of a linear equation. then the ordered pair must satisfy the linear equation
In this problem we have
<u>verify each case</u>
case A)
substitute the value of x and the value of y in the linear equation and then compare
-----> is not true
therefore
The ordered pair case A) is not a solution
case B)
substitute the value of x and the value of y in the linear equation and then compare
-----> is true
therefore
The ordered pair case B) is a solution
case C)
substitute the value of x and the value of y in the linear equation and then compare
-----> is not true
therefore
The ordered pair case C) is not a solution
case D)
substitute the value of x and the value of y in the linear equation and then compare
-----> is not true
therefore
The ordered pair case D) is not a solution
