Answer:
a. correlation
b. inverse linear correlation exists If the higher the population of students lead to a decrease in test score, 
c. yes
Step-by-step explanation:
a. Correlation is a measure of the amount of association existing between two variables. 
b. For linear correlation, if points are plotted on a graph and all the points lie on a straight line, then perfect linear correlation is said to exist. When a straight line having a positive gradient can reasonably be drawn through points on a graph positive or direct linear correlation exists, 
Similarly,when a straight line having a negative gradient can reasonably be drawn through points on a graph, negative or inverse linear correlation exists,
The results of this determination give values of r lying between +1 and −1, where +1 indicates perfect direct  Positive linear correlation and −1 indicates perfect inverse correlation or Negative linear correlation and 0 indicates that no correlation exists. 
If the higher the population of students lead to a decrease in test score, there will definitely be a negative correlation between class size and test score. i.e low class size result in high test score which consequently lead to high performance.
c. YES
A negative correlation means low class size result in high test score which consequently lead to better performance.

The point-slope equation of the line is 
Step-by-step explanation:
The form of the point-slope equation is  , where
 , where
- m is the lope of the line
 is a point lies on the line is a point lies on the line
The slope of a line  , where
 , where
 and
 and  are two points on the line
 are two points on the line
∵ The line through (2 , 3) and (7 , 4)
∴  = 2 and
 = 2 and  = 7
 = 7
∴  = 3 and
 = 3 and  = 4
 = 4
- Substitute these value in the rule of the slope
∵ 
∴ the slope of the line is 
Let us substitute the value of the slope and the coordinates of point  in the form of the equation
 in the form of the equation
∵ 
∵  = 2 and
 = 2 and  = 3
 = 3
∵ 
∴ 
The point-slope equation of the line is
