The correct answer is) D.  Because on the graph you can see that it increases by 25 each day which follows the equation Y=25x 
The reason for this is because she reads 25 pages a night Meaning that the total number of pages Jacqueline has read (Variable Y) = 25 pages a night (x)

Step-by-step explanation:
 
        
                    
             
        
        
        
Ok, sin = prep / hyp    
so,  perpendicular  = 1  , and hypo = 4  
so, base = sq. root ( 16-1 ) = root 15
and tan = prep / base  = 1 / root (15)
