Answer:
The means is 8.5 The Median is 6
Step-by-step explanation:
1) to find the mean just Simply add all the numbers together and divided by how many numbers that is giving. (Because you are simply finding the average)
9+6+5+3+28+6+4+7=68
68 divided by 8 = 8.5
2) to find the median simply organize the numbers from least to greatest Like this: (3,4,5,6,6,7,9,28) Then keep crossing out from both sides teal you find the middle Number.
If there a odd amount of number the median will be one Number, if even 2 numbers ( if 2 numbers just add them both and divide by 2)
In This Case the Median is 6,6 but Its actually 6 Why (6+6=12) and (12/2=6) so your median is 6.

Answer:
B
Step-by-step explanation:
(5, -1) and (-5, 2)
y=-3/10x+1/2
-1= 3/10 (5) + 1/2
-1 = -15/10 + 1/2
-1 = -1.5 + 0.5
-1 =-1
20 (so you can give the other person brainliest)
