Question

The midpoint of a line segment with end points as (2, 3) and (4, y2) is (3, 2). What is the value of y2?
Answer
-2
-1
1
7

Answer 1

We know that the y-coordinate of the mid-term is the average of the other two, so
3+y^2=2
Can you solve for y?

Answer 2

Sorry, it's
(1/2)(3+y^2)=2

Answer 3

no i dont know how

Answer 4

(1/2)(3+y^2)=2
multiply both sides by two:
(3+y^2)=2*2=4
subtract 3 from each side:
y^2 = 4-3 =1
