Answer: OPTION D.
Step-by-step explanation:
The formula that is used to calculate the slope of a line is:
Where 
and 
are two points on the line.
In this case the student finds the slope of the line that passes trough these points:
You can notice that she writes in the numerator that:
So she chose the point 
as and the point 
as .
Then 
and 
in the denominator must be:
Therefore, she did not keep the order of the points the same in the numerator and the denominator.
Answer: The option B. 1.9 is correct
Explanation:
We are given the below information:
x Probability P(x)
0 0.2
1 0.1
2 0.4
3 0.2
4 0.1
The expected value of x is given below:
Therefore, the expected value of x is 1.9
Y-2= -3/4(x-6)
y=-3/4(x-6)+2
y=-3/4x+9/2+2
y=-3/4x+13/2
so for example if x=1 then y=5.76
or if x= 5 then y=2.75
