| 2 | 50 |
| 3 | 70 |
| 4 | 90 |

Idk where to start 😐
if it is linear it has a constant slope.
slope is ychange/xchange
Since all the x changes are the same, from step to step,
just check to see whether y always changes by the same amount. It does not.
So, not linear.
Now, if the first line were "1 30" then it would be linear.
