Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points

and

is

So the midpoint of your segment is

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.
Answer: c. 22X
Step-by-step explanation:
I think a and y is 2 and 3 because in order to get 5 you have to add
The equation is <span>y = -x + 2</span>
The expanded form is adding all the digits so the answer is
700+50+7+0.9+0.02+0.003
