Question

The table shows how much a painter charges for painting a home. Is the relationship shown linear? Explain.

| hours worked | amount charged |
———————————————
| 1 | 35 |
| 2 | 50 |
| 3 | 70 |
| 4 | 90 |
———————————————

Answer 1

Idk where to start 😐

Answer 2

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.
