Question

Which of the following data tables shows a linear relationship?

Answer 1

For this case we need to check if we satisfy the following:

y= kx

For the first table we have:

`m=(1+5)/(1+2)=(7-1)/(3-1)\\e(15-7)/(7-3)`

For the second case:

`m=(-1+13)/(-1+6)\\e(5+1)/(3+1)`

For the third case:

`m=(-5+9)/(-2+4)=(7+5)/(4+2)=(23-7)/(12-4)=2`

For the fourth case

`m=(-4+2)/(0+3)\\e(14+4)/(5-0)`

then the correct solution would be

Third option
