f(x) = mx + b
m = slope = -5
f(2) = 10 = (-5)(2) + b
b = 10 + 10 = 20
Ans. m=-5, b = 20

is a polynomial, leading coefficent 19.
(standard form: is what I wrote even near that? :)) )
Answer:
The difference in minutes of median collection times before and after the well was installed is: 25
Step-by-step explanation:
Before--
Clearly after looking at the whisker-box plot we could observe that the middle line in the box represents the median of the data.
Hence we have :
Median(M)=53
After--
Similarly looking at the box-whisker plot we could observe that the line in the box is at 28.
Hence, Median of the box after installing the well is(M'): 28
Hence,
The difference in Median is calculated as:
M'-M
= 53-28
= 25
Hence, the difference in minutes of median collection is:
25 minutes.
The answer is 9. because... (8+9) + 32= 49
