we have the equation
6x+4y=16
Remember that
If an ordered pair is a solution to the given equation, then the ordered pair must satisfy the given equation
so
Verify each ordered pair
N 1 (4,0)
For x=4 and y=0
substitute in the given equation
6(4)+4(0)=16
12=16 is not true
the ordered pair is not a solution
N 2 (-10,-9)
For x=-10 and y=-9
6(-10)+4(-9)=16
-60-36=16 is not true
the ordered pair is not a solution
N 3 (2,1)
For x=2 and y=1
6(2)+4(1)=16
12+4=16
16=16 is true
the ordered pair is a solution
N 4 (8,-8)
For x=8 and y=-8
6(8)+4(-8)=16
48-32=16
16=16 is true
the ordered pair is a solution
N 5 (-10,19)
For x=-10 and y=19
6(-10)+4(19)=16
-60+76=16
16=16 is true
the ordered pair is a solution
