Question

Complete the table of ordered pairs for the linear y=2x-8

Answer 1

Given:

Consider the below figure attached with this question.

The linear equation is:

`y=2x-8`

To find:

The values to complete the table of ordered pairs for the given linear equation.

Solution:

We have,

`y=2x-8`

Substituting
`x=0` in the given equation, we get

`y=2(0)-8`

`y=0-8`

`y=-8`

So, the value for first blank is -8.

Substituting
`y=-2` in the given equation, we get

`-2=2x-8`

`-2+8=2x`

`(6)/(2)=x`

`3=x`

So, the value for second blank is 3.

Substituting
`x=2` in the given equation, we get

`y=2(2)-8`

`y=4-8`

`y=-4`

So, the value for third blank is -4.

Therefore, the required complete table is:

x y

0 -8

3 -2

2 -4
