Question

which of the ordered pairs (2,9), (7, - 4), and (4, - 5) are in the relation given by 3x + 2y = 2?
(type an ordered pair. use a comma to separate answers as needed.)

Explanation:

Step1: Test (2,5) in the equation

Substitute $x=2$, $y=5$ into $3x+2y$:
$3(2)+2(5)=6+10=16$
Compare to 2: $16
eq2$

Step2: Test (0,-4) in the equation

Substitute $x=0$, $y=-4$ into $3x+2y$:
$3(0)+2(-4)=0-8=-8$
Compare to 2: $-8
eq2$

Step3: Test (4,-5) in the equation

Substitute $x=4$, $y=-5$ into $3x+2y$:
$3(4)+2(-5)=12-10=2$
Compare to 2: $2=2$

Answer:

$(4, -5)$
