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:
(x+y)/xy or (1/x + 1/y) portion of the leaves
Step-by-step explanation:
Let the total work done to rake the leaves be a for representation.
Thus,
given Maya takes x minutes to rake the leaves
thus,
work done by may in x minutes = a
dividing both side by x
work done by maya in x/x = 1 minutes = a/x
similarly
given Calra takes y minutes to rake the leaves
thus,
work done by may in y minutes = a
dividing both side by y
work done by maya in y/y = 1 minutes = a/y
__________________________________
Total work done by both in 1 minutes = a/x + a/y = a(1/x+1/y) = a(x+y)/xy
Thus, if a is the total work , then they do (x+y)/xy of a work in one minute.
Thus, (x+y)/xy portion of leaves do they rake in one minute if they work together.
40 can be gotten by multiplying 10 & 4
28 can be found by adding 10 + 10 + 4 + 4
so the side lengths are 4 & 10
The answer is 6 btw it’s wrong!
