Answer:
-7
Step-by-step explanation:
The slope formula is (y1 - y2) / (x1 - x2).
In this question we have two points: (1,5) and (2,-2).
x1 = 1
y1 = 5
x2 = 2
y2 = -2
then, plug in these numbers into the slope formula
(5-(-2))/(1-2) = 7 / -1 = -7
The range is the number of units between the smallest and largest number. organising your numbers from smallest to largest:
12, 19, 20, 28, 34, 36, 45, 45
in your case 12 is the smallest number of your set. lowering it to 3 would increase the distance between the two numbers, therefore increasing the range

I think the correct answer would be both the mean and median are appropriate measures of center. Since the given data set is ordinal and is not skewed that much. Also the values of such would be close with each other. Hope this answers the question.
