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.
