Problema Solution
We are driving diagonally cross country from Portland, OR, to a city Southeast in the USA. We know that the midpoint of our drive can be represented as (x1+x2)/2, (y1+y2)/2. If we know that x1=500&y1=200, what would be the midpoint if y2=600?(and we require (x1+y1)=(x2+y2))
Answer provided by our tutors
We know that the midpoint of our drive can be represented as:
((x1+x2)/2, (y1+y2)/2)
Also we know that
x1 = 500
y1 = 200
y2 = 600
We use (x1+y1)=(x2+y2) to find x2:
500 + 200 = x2 + 600

x2 = 100
Plug the values x1 = 500, y1 = 200, x2 = 100 and y2 = 600 into (x1+x2)/2 and (y1+y2)/2
(500+100)/2 = 300
(200 + 600)/2 = 400
The midpoint would be (300,400).
