Answer:
4
Step-by-step explanation:
look at the points that are intersected by the line. the first one is (2,8). put it in as Rise/Run to find the slope. you "rise" 8, and "run" 2 
so 8/2 is the slope. 
usually you need to simplify it.
8/2 = 4
 
        
             
        
        
        
Answer: A) 23
Step-by-step explanation:
3^2 + ( 6 - 2 ) ⋅ 4 -6/3
3^2 + 4 ⋅ 4 -6/3
9 + 4 ⋅ 4 -6/3
9 + 16 -6/3
25 - 6/3
75/3 -6/3 = 69/3
69/3 = 23
