Question

Complete the remainder of the table for the given function rule: y = -2x - 7

Answer 1

To complete the table you have to replace the given function with every given value of x and calculate the corresponding value of y.

The equation of the function is:

`y=-2x-7`

1) For x=-3

`\begin{gathered} y=-2x-7 \\ y=-2(-3)-7 \\ y=6-7 \\ y=-1 \end{gathered}`

2) For x=0

`\begin{gathered} y=-2x-7 \\ y=-2\cdot0-7 \\ y=-7 \end{gathered}`

3) For x=3

`\begin{gathered} y=-2x-7 \\ y=-2\cdot3-7 \\ y=-6-7 \\ y=-13 \end{gathered}`

4) For x=4

`\begin{gathered} y=-2x-7 \\ y=-2\cdot6-7 \\ y=-12-7 \\ y=-19 \end{gathered}`

The complete table is then:
