week 21
Step-by-step explanation:
first I did 37-9 and got 28 I divide that by 7 ( seven weeks) and got 4 so I know the slope is 4.
so to find how many weeks till 93 I did; 93 = 4x + 9. We have to get x by its self so I minus 9 by both sides and got 84 = 4x. So now we divid both sides by 4 to get x by its self and we end up with 21 = x
