Which equation is not a linear function?
y = 2 - 3
y = 3x
y=73
y = x + 3

I believe it is the first one y= 2 - 3

Step-by-step explanation:

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.
