I need help with two problems. I need the midpoint.?

Question

1. (-1.4,3.2), (2.6,-5.4)

2. (3.4,2.1), (7.8,3.6)

Thanks.

Answer 1

For each problems, just average the x's and average the y's.

1. x = (-1.4 + 2.6)/2 & y = (3.2 + -5.4)/2
Simplify that and put x and y into a coordinate:
(0.6, -1.1)

2. x = (3.4 + 7.8)/2 = 5.6 & y = (2.1 + 3.6)/2 = 2.85

Answer 2

Just subtract the two.
