Answer:
3) 3x - y = 1
Step-by-step explanation:
m=3
(y-2) / (x-1) = 3
y-2 = 3(x-1)
y = 3x - 1
Y + 12 = y + 10 + 2
y + 12 = y + 12
y - y = 12 - 12
0 = 0
True for all y
hope this helps!

a) Sample mean: 48.71
Sample median: 48.3
Sample variance: 5.41
Sample standard deviation: 2.37
Step-by-step explanation:
a) Sample mean:

Sample median: M=48.3
Note: I order the data increasingly and take the value N / 2 = 40. In this way there are 39 values above and 39 values below the median.
Sample variance:

Sample standard deviation
