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

- anonymous

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

- anonymous

-4,6

Wait where did you get 9 from? zale101

- Zale101

oh i'm sorry lol

- Zale101

So here we have ((2+(-6))/2,(-3+5)/2) =

- anonymous

its ok i messed up too. it's 2, 3/2 or 7/2?

- Zale101

((2+(-6))/2= -2
(-3+5)/2= 1

- anonymous

oh ok. what's next?

- Zale101

the slope is (change in y)/(change in x)

- Zale101

or (y2-y1)/(x2-x1)

- Zale101

So (5+(-3))/(-6+2) = ?

- anonymous

averages?

- 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

solve this for me (5+(-3))/(-6+2) = ?

- anonymous

sooo -3-5/2+6 = -8/8?

- Zale101

which equals -1

- anonymous

so then after that i just do y-y1= -1(x1-x. which is y+3=-1(x-5)?

- Zale101

1 and -2 are the midpoints

- anonymous

so (y-1)=-1(x=2)?

- Zale101

this means the midpoint is (-2,1)

- Zale101

x=-2
y=1

- anonymous

so then what comes after finding the midpoint

- Zale101

|dw:1371860805417:dw|

- Zale101

You are trying to find the midpoint of the endpoint points (2, -3) and (-6, 5).

- anonymous

omg i forgot to put what the slope... I'm sorry lol
slope=9/7

- Zale101

|dw:1371861044750:dw|

- Zale101

That's fine, but u need to keep in mind what's endpoint and what's midpoint

- Zale101

midpoint means middle point
endpoints means end of the line points

- anonymous

i know what midpoints and endpoints are.

- Zale101

Ok :)

- Zale101

just making it clear for u

- anonymous

ok. but what comes after we find the midpoint?

- Zale101

Use this formula to find the the point-slope form of a line
y - y1 = m(x - x1)

- Zale101

so we should plug in the numbers y - 1 = (9/7)(x - -2)

- Zale101

then simplify

- anonymous

"The line with slope SOMETHING MISSING HERE and containing the midpoint of the segment whose endpoints are (2, -3) and (-6, 5)."

- anonymous

Ohhhh! so its 9x-7y=-24

- 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

Hope i helped, sorry for taking your time

- anonymous

its ok. thanks for the help! :)

- Zale101

no problem :)
