Question

A line segment on the coordinate plane has endpoints (2,4) and (4,y) and the midpoint of the segment is point (3,7), What is the value of y?

Answer 1

4+y=2(7)

=14

y=14-4=10

Answer 2

Answer:

M = X1 + X2 41 + Y2

Which we are given M to be (3,7) So we can put in the information we know

into the formula (3,7) , (2 + 4 4+ Y)

which we can observe that we need to solve for:

4 + y2 - = 7

2

Which gives us:

4 + Y2 14

Y2 10 which is the answer to our question

thus our end point will be (4, 10)
