(0/4) = a slope of zero, because zero divided by any number is zero.
*For example, if you had zero cookies to hand out to four people and had to divide that number evenly by each person, each person would get zero cookies.
(4/0) = undefined slope, any number divided by zero is an undefined slope.
*For example, if you had four cookies to hand out evenly to people, but there is no one to hand them out to, it is impossible.
Find the slope intercept equation when given the slope and a point:
1.) m = 4 , (2,6)
2.) m = 4/8, (8,8)
3.) m = -5, (0,7)
4.) m = -2, (3,-6)
