Answer: C) Tracy spends $7 every 4 days
Graphing the function as well as x = 4 will show that there is a difference in the y-value of 7 between x=0 and x=4, meaning she spends $7 every 4 days.
Slope is change in y over change in x.
Change in y is -9
Change in x is +12
So -9/12 or -2/3
Answer -2/3

I think it's C. 0
Step-by-step explanation:
On Edge
T1 = 4
4 = a
T5 = 16
16 = 4 + 4d
4d = 12
d = 3
Tn = 4 + ( n - 1 ) 3
Tn = 4 + 3n - 3
Tn = 3n + 1
the answer is b
