ok, i'm confused.
here's the question:
Find the y-coordinate of the midpoint of segment MN with endpoints M (-2,6) and N (8,0).
there is like no picture whatsoever. i'm really confused.
Help! :)

Just take the arithmetic means of the coodinates of the endpoints, So, if (x,y) is the midpoint, then x = (-2 + 8)/2 = 3 and y = (6 + 0)/2 = 3

The midpoint of the line segment is just the average of the endpoints ( (8-2)/2, (0+6)/2 ) = (3,3).
The y-coordinate of the midpoint is 3.
Coincidently, the x-coordinate of the midpoint is also 3.

The midpoint of a segment has as it x the midpoint of the x's of the endpoints. Thus, the midpoint of -2 and 8 is x=3.
Now, you figure it out the same way for the y's.

Midpoint is 3,3. Take your to x terms 8 and -2 and calculate how far apart they are. They are 10 because 8--2 = 8+2=10. Divde that by 2, and you get 5. Then you split the difference and get three. You do the same for the y terms and you also get three because 6+0=6 and 6/2=3. Hope that helps.

You might try starting by drawing a grid and plotting the points you already have.

x=(-2+8)/2=6/3=3
y=(6+0)/2=3
midpoint is (3,3)
