Answer:

347 is the initial spider population

Step-by-step explanation:

y = ab^x

is the formula for exponential growth and decay

a = the initial value

b is the growth or decay rate

b>1  it is the growth rate  (b-1) is the percent

0<b<1 it is the decay rate (1-b) is the percent

y = 347(1.2)^x

347 is the initial spider population

(1.2-1) = .2 = 20 % growth rate

Using the slope and the y intercept, graph the line represented by the following equation.
PtichkaEL [24]
Beforehand let me apologize for my sloppy handwriting. I'm a lefty, so please deal with me. . Anyway, the equation you listed didn't really have a x, because a linear equation is y= mx+b, and anything with x is the slope. But I did see y and a number on one side, so I'm like maybe I can get these two alone. So here's what I did:

2y + 4=0
-4 -4 I subtracted 4 on both sides. Why because you would want "y" alone.
Next,
2y= -4
Now to get "y" alone you want to divide on both sides.
2y= -4/ 2
y= -2
Now you're probably thinking "how do you graph it? There's no "x" in the equation." Well, you just graph it. Since the answer is y= -2, you go to the y axis, look for -2, and place a line to indicate that is the equation. And to make it clear, remember y is the y-intercept.

I really do hope this helps you, if not message me. I'll be happy to help, and again I'm sorry for my handwriting!
