Steps:
1. You find the slope of the ordered pairs using the slope formula
Y2-Y1
--------
X2-X1
2. You use the slope and one of the ordered pairs to do the points slope form
Y-Y1=m(x-x1)
For example: (-2, 2) and (4,2)
1.
2-2
------
4 +2
2.
2-2= 0
4 + 2= 6
3. Your slope would be 0 since 0/6=0
4. Y-2= 0 (x-4)
