Question

What happens to the value obtained for the slope if the coordinates of the two ordered pairs aren’t subtracted in

the same order? Give an example as part of your explanation.

Im not sure what this is asking?

Answer 1

say (0,0) and (1,1)

slope = (1-0)/(1-0) = 1
now the other way
slope = (0-1)/(0-1) = -1/-1 = 1
No change
the sign of both top and bottom change so the result does not change. note: -a/-b = a/b
