Answer: choice A) -8/5

=====================================================

Work Shown:

Use the slope formula which basically says you subtract the y coordinates, then subtract the x coordinates in the same order, then you divide the results (reduce if possible)

m = (y2-y1)/(x2-x1)

m = (-1-7)/(4-(-1))

m = (-1-7)/(4+1)

m = -8/5

m = y2 - y1/ x2 - x1

m = -1 - 7/ 4 + 1

m = -8/5
