Question

Check all of the ordered pairs that satisfy the equation below. y =2/5x

Answer 1

`y=(2)/(5)x`

we can try the options replacing and look the equality

A.

`\begin{gathered} (5)/(2)=(2)/(5)(25) \\ \\ (5)/(2)=10 \end{gathered}`

so, A its wrong

B.

`\begin{gathered} 24=(2)/(5)(40) \\ 24=16 \end{gathered}`

So, B its wrong

C.

`\begin{gathered} 20=(2)/(5)(50) \\ 20=20 \end{gathered}`

So, C is right

D.

`\begin{gathered} 12=(2)/(5)(30) \\ 12=12 \end{gathered}`

so, D its right

E.

`\begin{gathered} 4=(2)/(5)(10) \\ 4=4 \end{gathered}`

So E, its right

F.

`\begin{gathered} 35=(2)/(5)(14) \\ 35=5.6 \end{gathered}`

So, F its wrong
