This is a perfect example of exponential decay. In this case the growth factor should be represented by a fraction, and it is! This forest, starting out with apparently ( 800? ) pine trees, has a disease spreading, which kills 1 / 4th of each of the pine trees yearly. Therefore, the pine trees remaining should be 3 / 4.
Respectively 3 / 4 should be the growth factor, starting with 800 pine trees - the start value. This can be represented as such,
- where a = start value, b = growth factor, t = time ( <em>variable quantity</em> )
____
Thus, the function
can model this problem. The forest after t years should have P( t ) number of pine trees remaining.

I dunno actually D: I think it's 1.6 sorry I really don't know leave a 1 star if you have to!
Answer:
slope = 3
y-intercept = -4
y = 3x-4
Step-by-step explanation:
Answer:
It's B
Step-by-step explanation:
Just divide y by x. For example: 6.6 / 6 = 1.1. This would be B! Hope this helps!
