It is y = 3x + 2, which means the y-intercept is 2. :)
I pretty sure the answer would be B :)
y = a(1 + r)ˣ
a = 15 "<em>initial" means what you started with on the first day</em>
r = 6 <em>the rate it increased is the slope (
</em>
y = 15(1 + 6)ˣ
Answer: y = 15(7)ˣ
Step-by-step explanation:

First, let's move all of the terms with an
to the left-hand side of t he equation, and everything else to the right-hand side of the equation.


Next, let's divide both sides by
to isolate the
variable by itself on the left-hand side of the equation:
