Find the slope of the line that goes through the points (-1,4) and (4,-8).

Step-by-step explanation:

Slope formula: m = y2-y1 ÷ x2-x1 OR m= y2-y1/x2-x1

Point (-1,4): -1 is considered x1 and 4 is considered y1

Point (4,-8): 4 is considered x2 and -8 is considered y2

Substitute into equation:

m = y2-y1/x2-x1

m = -8-4/4-(1)

m = -12/5

You cannot simplify further so the slope of the line is (-12,5)

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
