## LoveYou*69 one year ago I tried this once:P but the answer I came out with wasn't right: M is the midpoint of segment AB. Find the coordinates of B given A(-5,1) and M(-2,4). Use the formula for this which is: (to find the x coordinate of B) x-coordinate of M = x-coordinate of A + x-coordinate of B /2 (to find the y coordinate of B) y-coordinate of M = y-coordinate of A + y-coordinate of B /2

$To Solve For The X-coordinate Of B: -2 = \frac{ -5 + x }{ 2 }$ $ToSolveForTheY-CoordinateOfB: 4 = \frac{ 1 + y }{2}$

I messed up solving for x & y somehow the first time, anyone want to help me out?(:

3. Hero

You can use graph paper to find the coordinates of B

4. Hero

Since AB is a line segment, the slope of AM = Slope of MB

5. LoveYou*69

Yeah, but I need to see how to solve it this way, cause I tried but messed up. :P

6. Hero

Did you at least figure out what the coordinates of B?

7. LoveYou*69

lol no:p

8. Hero

Well, that would be a good start. If you use graph paper, you would be able to figure out the points. Then after that, you could use the midpoint formula easily, since you'd already know the coordinates of B.

B(1,7)?

10. Hero

|dw:1358964289133:dw|

11. Hero

Yes, B = (1,7) Correct

12. Hero

Notice, if you solve each of those equations you wrote above, you will find x and y as well.

13. Hero

Now you know two ways to solve it. :D

lol thanks:)
