Answer:
-3
Step-by-step explanation:
To find the slope of a line given two points, we use:
 .
.
Or you could line up the points vertically and subtract the points vertically, then put 2nd difference over 1st difference.
That looks like this:
 (  2  ,  -12)
-( -5  ,  9   )
----------------
   7         -21
So the slope is -21/7 which gives you -3.

Two negatives being multiplied DOES equal a positive 
In my response to is that is a correct term to answer. <span />
        
             
        
        
        
19/20 is the simplest form
        
                    
             
        
        
        
The first angle is 76 and the second angle is 14. You can check this by doing 14+5=19 and then multiply that by 4.
