When finding for the slope the formula is:
[tex]m= \frac{y_{2} - y_{1} }{ x_{2} - x_{1} } [/tex]
1. (2, -8) and (-1, 0)
0 - (-8)
m = --------- m = -8/3
-1 - 2
0 + 8 8
= --------- ⇒ ---------
-3 -3
2. (-5, 0) and (-1, 0)
Since the y-intercepts are both the same, then the slope would be automatically 0.
m = 0
3. (-4, 6) and (-1, 1)
1 - 6
m = ---------
-1 - (-4) m = -5/3
- 5
-------
3
4. (-5, 9) and (-2, 3)
3 - 9
m = --------
-2 - (-5) m = -2
-6 -6
-------- ⇒ ------ ⇒ -2
-2 + 5 3
5. (6, 0) and (8, 0)
Since both the y-intercepts are the same, m would be automatically 0.
m = 0
