y = 3x =3(6) = 18 ... the ordered pair is (x,y) = (6,18)
f(x)= 3x+2 x=5f(5)=3(5)+2f(5)=17y=17(5,17)
y=3x
It depends very much on what the question is!
There are an infinite number of ordered pairs that satisfy the equation.
-2,4
really depends. 12x - 8y = 48 3x - 2y = 12. You can't decide, but one ordered pair is (4,0)
The ordered pair is (5, 4).
-12
y=3x-5
{-4,-5}
