Question

Complete the table. 90 Chips Bag 3 1 9 14 Chips 90 Bag 3 1 9 14 (Type whole numbers or decimals.)

Answer 1

Let:

`\begin{gathered} (x1,y1)=(3,90) \\ (x2,y2)=(1,y) \end{gathered}`

let:

`y1=kx1`

where:

k = constant of proportionality:

`\begin{gathered} 90=3k \\ k=(90)/(3) \\ k=30 \end{gathered}`

so:

`\begin{gathered} y=30x \\ x=1 \\ y=30 \\ ---- \\ x=9 \\ y=270 \\ ---- \\ x=14 \\ y=420 \end{gathered}`

Answer:

From left to right:

30, 270, 420
