Answer:
87.5%
Step-by-step explanation:
It decreased by 16 - 2 or 14, and since he wrote 16 tickets last week, the answer is 14/16 in percent form, or 7/8 = 87.5%.
 
        
             
        
        
        
Answer:
the slope of line j is -1/8, the slope of lines m and n are both 8. 
Explanation step by step:
Suppose j is the slope of line j, m the slope of line m and n the slope of line n. Since: 
1. line j is perpendicular of line m, so j*m= -1 
2. J is perpendicular of line n, so  j*n=-1 
3. m and n and parallel so m=n 
As we want to know the slope of j we clear the equations presented to us in order to find it.
(1) m* n* j = -8, since n=m we have   * j = -8.
* j = -8.
we clear j; 
replacing in the equation n*j = -1 we get
n*(-8/n^2) = -1. Thus n = 8. Since j = -1/n = -1/8.
