Answer:
see graph
Step-by-step explanation:
Personally I put into slope intercept form before graphing
y - 3 = 1/2 (x+2)
y -3 = 1/2x + 1
y = 1/2x + 4
4 is y-intercept
1/2 is slope. 
Answer:
Students level of knowledge is higher in accountancy (Y) compared to statistics (X).
Step-by-step explanation:
The level of knowledge of the students in each subject can be known by comparing the mean score of the subjects.
Marks of the students in statistics (X) are: 63 64 62 32 30 60 47 46 35 28
mean = 
= 
= 46.7
The mean mark of students in statistics (X) is 46.7.
Marks of students in accountancy (Y) are: 68 66 35 42 26 85 44 80 33 72
mean = 
= 
= 55.1
The mean mark of students in accountancy (Y) is 55.1.
It can be inferred that students level of knowledge is higher in accountancy (Y) compared to statistics (X).
