The points l(10,9) m(10,-5) n(-1,-5) and o(-1,9) form rectangle l m n o which point is halfway between o and n.
a.) (-1,0)
b.) (-1,7)
c.) (-1,2)
d.) (2,-1)

  C.)  (-1, 2)

Step-by-step explanation:

You can plot the points on a graph, or you can just find the midpoint:

  midpoint = (O + N)/2 = ((-1, 9) +(-1, -5))/2 = (-1-1, 9-5)/2 = (-2, 4)/2

  midpoint = (-1, 2)

won't that be plagrisim thought?
