For the midpoint, we have to us this formula ((x1+x2)/2,(y1+y2)/2)

Was the slope given? It loks like you forgot to add it or no?

-4,6

Wait where did you get 9 from? zale101
Zale101
  • Zale101
oh i'm sorry lol
Zale101
  • Zale101
So here we have ((2+(-6))/2,(-3+5)/2) =
anonymous
  • anonymous
its ok i messed up too. it's 2, 3/2 or 7/2?
Zale101
  • Zale101
((2+(-6))/2= -2 (-3+5)/2= 1
anonymous
  • anonymous
oh ok. what's next?
Zale101
  • Zale101
the slope is (change in y)/(change in x)
Zale101
  • Zale101
or (y2-y1)/(x2-x1)
Zale101
  • Zale101
So (5+(-3))/(-6+2) = ?
anonymous
  • anonymous
averages?
Zale101
  • Zale101
Do you know how to plug in the numbers into the formula's, like what i did here for example (5+(-3))/(-6+2) = ?
Zale101
  • Zale101
solve this for me (5+(-3))/(-6+2) = ?
anonymous
  • anonymous
sooo -3-5/2+6 = -8/8?
Zale101
  • Zale101
which equals -1
anonymous
  • anonymous
so then after that i just do y-y1= -1(x1-x. which is y+3=-1(x-5)?
Zale101
  • Zale101
1 and -2 are the midpoints
anonymous
  • anonymous
so (y-1)=-1(x=2)?
Zale101
  • Zale101
this means the midpoint is (-2,1)
Zale101
  • Zale101
x=-2 y=1
anonymous
  • anonymous
so then what comes after finding the midpoint

  • Zale101
You are trying to find the midpoint of the endpoint points (2, -3) and (-6, 5).
anonymous
  • anonymous
omg i forgot to put what the slope... I'm sorry lol slope=9/7
Zale101
  • Zale101
|dw:1371861044750:dw|
Zale101
  • Zale101
That's fine, but u need to keep in mind what's endpoint and what's midpoint
Zale101
  • Zale101
midpoint means middle point endpoints means end of the line points
anonymous
  • anonymous
i know what midpoints and endpoints are.
Zale101
  • Zale101
Ok :)
Zale101
  • Zale101
just making it clear for u
anonymous
  • anonymous
ok. but what comes after we find the midpoint?
Zale101
  • Zale101
Use this formula to find the the point-slope form of a line y - y1 = m(x - x1)
Zale101
  • Zale101
so we should plug in the numbers y - 1 = (9/7)(x - -2)
Zale101
  • Zale101
then simplify

"The line with slope SOMETHING MISSING HERE and containing the midpoint of the segment whose endpoints are (2, -3) and (-6, 5)."
anonymous
  • anonymous
Ohhhh! so its 9x-7y=-24
Zale101
  • Zale101
@satellite73, i actually read the question wrong lol from where did u get 24? 7y - 7 = 9x + 18 7y = 9x + 25 9x - 7y = -25
Zale101
  • Zale101
Hope i helped, sorry for taking your time

  • anonymous
its ok. thanks for the help! :)
Zale101
  • Zale101
no problem :)
