hi 
line equation is :  mx+p  
so if a  line goes throught  A(4;6) and with m = 3   so you have  3 *(4) +P = 6
so :   12 +P = 6 
             P = 6-12 
             P = -6 
line equation is  :   3m -6 
    
 
        
             
        
        
        
The population in the above situation is the total number of students under Mr. Wilson. 
A sample is a part of the population that may best represent the population. There is no sample  in the above situation because Mr. Wilson made all students pick 5 note cards. He will be able to determine the performance of each student based on their performance in picking 5 note cards and defining the terms in each card.
