Answer:
slope= (y2-y1)/(x2-x1)
1) (2-1)/(3-2)
=m=1
3) (5-4)/(2-2)
= UNDEFINED (vertical line)
5) (-6-6)/(3-(-3)
(-12/6)
= -2
CHECK
y=mx+b
6=-2(-3)+b
6=6+b
b=0
y=-2x connects both of these points on a graph
m = rise over run
Rise: y/2 - y/1
Run: x/2 - x/1
m = slope
(x_1, y_1) = coordinates of first point in the line
(x_2, y_2) = coordinates of second point in the line
