slope = (y2-y1)/(x2-x1)
the first slope is 0 (horizontal line)
second slope is undefined (vertical line)
Its different because when u add 645 and 738 it equals 1,382 and when u add 645 and 649 it equals 1,294 so 1,382 is the greater number and its different from 1,294<span />
I belive it is the second option!
