The slope is -3.
Finding slope can be easy if you just remember that the formula is set up as y=mx+b.
The number in the 'm' place is always the slope.
Example: y=4x+1, the slope would be 4 because it's in the 'm' place.
If you have trouble remembering which place the slope is, trying thinking about skiing or sledding; you can only sled or ski down a Mountain slope. Mountain starts with M.
M=slope.

Answer:
Fraction : 3/9
Decimal : 0.33333333 (the .3 continues)
Percent : 33.33333%
Step-by-step explanation:
Dividing 3 by 9 will give you a continous set of 3.
Answer:
![D(t)=-24t+166](https://tex.z-dn.net/?f=D%28t%29%3D-24t%2B166)
Step-by-step explanation:
Let
D(t) = the distance to the safe zone (measured in meters)
t = time (measured in seconds)
<u>Given:</u>
Rachel's rate = 24 meters per second
At
seconds
meters
<u>Find:</u> D(t)
Rachel's rate is the slope of the function D(t). Since the distance is decreasing when the time is increasing, the slope must be negative.
Hence, the function expression is
![D(t)=-24t+b](https://tex.z-dn.net/?f=D%28t%29%3D-24t%2Bb)
To find b, substitute
and ![D(t_1)=70:](https://tex.z-dn.net/?f=D%28t_1%29%3D70%3A)
![70=-24\cdot 4+b\\ \\70=-96+b\\ \\b=70+96\\ \\b=166](https://tex.z-dn.net/?f=70%3D-24%5Ccdot%204%2Bb%5C%5C%20%5C%5C70%3D-96%2Bb%5C%5C%20%5C%5Cb%3D70%2B96%5C%5C%20%5C%5Cb%3D166)
So,
![D(t)=-24t+166](https://tex.z-dn.net/?f=D%28t%29%3D-24t%2B166)
So just add all of them together and you get 405. Then divide by the amount of numbers there is which is 5. So 405 divided by 5. The answer is 81.
