Question

check all of the order pairs that satisfy the equation below.
y= 2/3x

a. (21,3/2)
B. (7,14)
c. (21,14)
D. (28,42)
E. (42,28)
F (14,21)

Answer 1

helppp -.-

Answer 2

Take each ordered pair and plug it into the equation.
If it makes the equation true, then it satisfies the equation.
I'll use the first point as an example.

Equation
y = (2/3)x
a. Test (21, 3/2) in the equation
Is 3/2 = (2/3)*21?
3/2 = 14 is false, so (21, 3/2) does not satisfy the equation.

Answer 3

ok i get it but at the same time i dont so A. i know that one does not satisfy the equation but ok like i said still kinda lost

Answer 4

nevermind i got the answer i get now thanks for your help though (:

Answer 5

Let's do the third together as another example.

Equation:
y = (2/3)x
c. Test (21, 14)
We replace x in the equation with 21, and we replace y in the equation with 14.
Is 14 = (2/3) * 21?
14 = 14 True
So (21, 14) satisfies the equation.
