i told you exactly how to do itwhat part exactly are you having problems with?

how do u divide the final numerator by 2. i dont get this shit. the program on the computer shuts off after like 5 minutes and i cant answer the ****ing question. its rediculous. how do they expect kids to do homework online, some kids dont even have computers. by the time i leave work the library and shit is closed at the campus and my laptop doesnt like the program or some shit.

(x/y)/2 = x/(2y)

where did you hear that you had to get a common denominator?

I never did that with a common denominator, and I think that acidburn's answer may be wrong, beacuse the second set of coordinates exceeds the middle of the line.

so multiply the denomonator by 2 and divide the numerator by that?

i plugged exactly what he said into the exact equation he said

i have not actually calculated or thought about any of this

how else do u add two fractions together without a common denominator?

yes

alright, here is how to do it....: I think that each set of coordinates is a seperate problem.

take the X from the first coordinate: 3 add the second X coordinate : -4 you will have -1 on top. Take the first Y: 7 second Y : -3 add them, you will have 4 on the bottom, so the divide that by two. : x= -0.5 y= 2 I believe that is right, now you have the other one to do.

thats not how you do it, at all

the first X coordinate is 3/7

That is how I was taught, the 3/7 is the x/y

That is how I was taught, the 3/7 is the x/y

im sorry, but that is completely incorrect

a coordinate pair is set up like this: ( x , y )

Well, I think it would be very hard to graph 3/7's of a unit. Well maybe Iam wrong, but it always worked for my algebra teachers, I had it 2 years back to back, and was just using it in geometry about 3 months ago. Maybe iam just mixing geometry into algebra, but I think it would be impossible for the midpoint to be farther then the endpoint. Iam gonna go to bed, been up too long.

since when did the world only use whole units?

and the method he says will give a midpoint that's in between the 2 ends, it's just like taking an average
