Question

which ordered pair is a solution of the equation y=x-4

Answer 1

(2,6)
(6,2)
(-2,6)
(-6,2)

Answer 2

(x, y)

also, the eq states y to always be 4 smaller than x

Answer 3

wait, what?

Answer 4

a solution means when you replace the x and y with the numbers they give you, the equation is true.

for example, is (2,6) a solution of
y = x -4
?

(2,6) is short for let x=2 and y=6. use those numbers in y=x-4
6 =? 2 -4
2-4 is -2 and we get
6 = ? -2 NO. (2,6) is not a solution

test the other pairs of numbers. Do any work ?
