Answer:
-1/2
Step-by-step explanation:
The question is asking for the slope of the line. The standard form of a linear equation is y=mx+b where m is the slope. To find the slope you simply look at the change in y over the change in x. You can pick any two coordinate points to find the slope.
Here is the equation to find the slope;
****Notice that the line starts up high (looking at it from left to right, like how you read a book), and therefore it is a negative slope.
I am picking the points (-1,2) and (1,1). Plug in the corrdinates- (2-1=1) and (-1-1=-2) -1/2
Hope this helps:)

Question:
A population of insects, in thousands, can be modeled using the function
, where t is time in months. Which statement best
describes the population of insects?
A. The population is decaying at a rate of 3% each month.
B. The population is decaying at a rate of 25% each month.
C. The population is growing at a rate of 75% each month.
D. The population is growing at a rate of 97% each month.
Answer:
A. The population is decaying at a rate of 3% each month.
Step-by-step explanation:
Given
Required
True statement about the function
From the options, we can see that we are to answer the question on the basis of decay and growing rates.
An exponential form is:
Compare to
If , then
r represents growth rate
else, r represents decay rate
Since b < 0.97:
