OB. 14, 9,4
c.
13, 7,1
D.
-1, -7, -13

Answer 1

C 13,7,1

Explanation:

The given expression is
`y=-3x+7`.

To find the corresponding y-values, we need to plug in the x-values.

When x=-2,
`y=-3(-2)+7`,
`\implies y=6+7=13`

When x=0,
`y=-3(0)+7`,
`\implies y=0+7=7`

When x=2,
`y=-3(2)+7`,
`\implies y=-6+7=1`

Therefore the numbers that completes the table are: 13,7,1

The correct answer is C
