Answer:
0.16/8.5 
Step-by-step explanation:
so to get the slope use (Y2-Y1) over (X2-X1) 
this means that the formula is 
1/2-1/3
---------
25.5- 17
 
        
             
        
        
        
Answer:
n=7/3
Step-by-step explanation:
 1 (n – 4) – 3 = 3 - (2n+3)
1. distribute the 1 on the left side and distribute the -1 on the right side
1n-4-3=3-2n-3
2. add like terms
1n-7=-2n
3. move n to one side and by itself
-7=-3n
4. divide -3 to get n alone. Both negatives cancel out each other
7/3=n
