PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!

Answer: $\bold{-\dfrac{1}{2}}$

Step-by-step explanation:

Average rate of change is the slope (m) between the two coordinates (-1, -1) and (1, -2).

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m = \dfrac{-2+1}{1+1}$

$=-\dfrac{1}{2}$

Please help thx a bunch

kirza4 [7]

A.
2/3A=-24
time both sides by 3/2
A=-72/2
A=-36

B.
20=-B/0.2
times both sides by 0.2
4=-B
times -1
-4=B

distance between 2 points x and y is |x-y|

so
distance between A and B is distance between -4 and -72 or
|-72-(-4)|=|-72+4|=|-68|=68
the distance is 68
