Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that’s non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.

Explanation:n
In table 1,n
The slope can be obtained as follows,n
[tex]begin{aligned}m&=frac{{ – 6 + 2}}{{2 – 1}}&=frac{{ – 4}}{1}&= – 4end{aligned}[/tex]
The slope of other two points can be obtained as follows,n
[tex]begin{aligned}m&= frac{{ – 2 + 6}}{{3 – 2}}&= frac{4}{1}&=4end{aligned}[/tex]

The slope is not equal. Therefore, table 1 is not correct.n
n
In table 2,n
The slope can be obtained as follows,n
[tex]begin{aligned}m&= frac{{ – 5 + 2}}{{2 – 1}}&=frac{{ – 3}}{1}&= – 3end{aligned}[/tex]
n
The slope of other two points can be obtained as follows,n
[tex]begin{aligned}m&=frac{{ – 9 + 5}}{{3 – 2}}&= frac{{ – 4}}{1}&= – 4end{aligned}[/tex]
n
The slope is not equal. Therefore, table 2 is not correct.n

In table 3,n
The slope can be obtained as follows,n
[tex]begin{aligned}m&= frac{{ – 10 + 2}}{{2 – 1}}&= frac{{ – 8}}{1}&= – 8end{aligned}[/tex]
n
The slope of other two points can be obtained as follows,n
[tex]begin{aligned}m&= frac{{ – 18 + 10}}{{3 – 2}}&= frac{{ – 8}}{1}&= – 8end{aligned}[/tex]
n
The slopes are equal. Therefore, table 3 is correct.n

In table 4,n
The slope can be obtained as follows,n
[tex]begin{aligned}m&= frac{{ – 4 + 2}}{{2 – 1}}&=frac{{ – 2}}{1}&= – 2end{aligned}[/tex]
n
The slope of other two points can be obtained as follows,n
[tex]begin{aligned}m&=frac{{ – 8 + 4}}{{3 – 2}}&= frac{{ – 4}}{1}&= – 4end{aligned}[/tex]
n
The slope is not equal. Therefore, table 4 is not correct.n
