Answer:
There is no slope
Step-by-step explanation:
The equation for finding the slope is:
y2 - y1
------------
x2 - x1
-----------------------------------------------------------------------------------------------------------
-9 - (-9)
----------- <----------------- Here is your starting equation
7 - (-9)
-------------------------------------------------------------------------------------------------------------
-9 + 9
---------
7 + 9
-------------------------------------------------------------------------------------------------------------
0
---
16
--------------------------------------------------------------------------------------------------------------
There is no slope because you can't divide 0 by 16
Hope that helps :)
