Question

Find the coordinates of the midpoint between point A(-5, -9) and the origin.
A. five-halves, nine-halves
B. (-5, -9)
C. negative five-halves, negative nine-halves
D. (5, 9)

Answer 1

to find the mid point we use the following formula
\[x =(\frac{ x _{1} + x _{2} }{ 2 } )\]

and for y
\[y = \frac{ y _{1} + y _{2} }{ 2 }\]

Answer 2

and since the co-ordinates of the origin are 0,0
=> x = ( -5 + 0 ) / 2 = -5/2
and y = (-9 + 0 )/2 = -9/2

hence A is the correct option... :)
