Answer:
The first is a solution, but the second is not
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 (makes the equation true)
we have
<u><em>Verify the first ordered pair</em></u>
Part a) we have (2,-9)
For x=2, y=-9
substitute in the linear equation
----> is true
so
The ordered pair satisfy the equation
The ordered pair is a solution of the equation
<u><em>Verify the second ordered pair</em></u>
Part b) we have (3,-6)
For x=3, y=-6
substitute in the linear equation
----> is not true
so
The ordered pair not satisfy the equation
The ordered pair is not a solution of the equation
