Answer:
f(x)=−5x−20
Step-by-step explanation:
It's decreasing 5 degrees every hour, which is represented by -5x
You also have to take away the 20 (-20) from where it started.
So, f(x)=−5x−20
Answer:
2,1
Step-by-step explanation:
T-5 .9(×,y)
-2,-3
=2,1
To know how far your values differ apart from the mean of the records
The answer is 38 degrees. It WOULD be -38, but difference can not be negative.
Hello.
There are really 2 ways to think about the given problem.
First, we can use the slope formula:


Slope = undefined
The second way is to just take a look at the points.
You should notice that the x-coordinates are the same.'
If the x-coordinates are the same, then the slope is

I hope it helps.
Have a nice day.
