Question

Which table of ordered pairs matches the following function? y=1/2×-1

Answer 1

`y=(1)/(2)x-1`

we need to cheack each table for each we must check each pairs replacing on the equation

1)

x=-2

`\begin{gathered} y=(1)/(2)(-2)-1 \\ y=-2 \end{gathered}`

x=-1

`\begin{gathered} y=(1)/(2)(-1)-1 \\ y=-1.5 \end{gathered}`

x=0

`\begin{gathered} y=(1)/(2)(0)-1 \\ y=-1 \end{gathered}`

x=1

`\begin{gathered} y=(1)/(2)(1)-1 \\ y=-0.5 \end{gathered}`

x=2

`\begin{gathered} y=(1)/(2)(2)-1 \\ \\ y=0 \end{gathered}`

all pairs in the first table match so the correct option is the first
