Answer:
slope = - 2
Step-by-step explanation:
calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (5, - 4 )
m = =

= - 2
The mean is the average value of numbers given in the series
The median is the middle value of the given series
The mode is the number that is appears more than any other number given in the series
Step-by-step explanation:
The given series is 31,1,27,23,15,27,25,18,22 (totally 9 numbers)
let us change them in a ascending order like 1,15,18,22,23,25,27,27,31
Mean = 21
Median = middle value of the series 1,15,18,22,23,25,27,27,31
23 is the median
Mode = 27 ( it appears in two times 1,15,18,22,23,25,27,27,31)
final answer is
Mean = 21
Median = 23 and
Mode = 27
