Question

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)

Answer 1

C.) (-1, 2)

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)
