What are the coordinates of the midpoint of KL¯¯¯¯¯ where K(3, 2) and L(−1, 4)? (1, −2) (1, 3) (3, 1) (2, 3)

Answer: (1,3) which is choice B

--------------------------------------------------------------------------------

Explanation:

Point K and point L have the x coordinates of 3 and -1 respectively. Add them up to get
3+(-1) = 2
Then divide that result in half giving
2/2 = 1
So the x coordinate of the midpoint is x = 1

Do the same for the y coordinates 2 and 4
Add them up: 2+4 = 6
Divide the result over two: 6/2 = 3
The y coordinate of the midpoint is y = 3

So that's why the midpoint is (1,3)
