algebra math, 8th grade
posted by Tazia
If point A is located at (0, -8) and B is located at (4, -5), what is the distance between them?
I know I don't usually ask for just the answer (I generally give what I got) but this was due on the 6th! I was in the hospital for pneumonia, and I didn't realize how behind I was in algebra. Please, please help as soon as possible!!
Please, please don't ban me. I just really need this. I'm panicking (I know, I'm such a suck-up), just please don't ban me. I'm not trying to cheat.
d =sqrt [ (y2-y1)^2 +(x2-x1)^2 ]
d =sqrt [ (-5 +8)^2 +(4-0)^2 ]
= sqrt [ 9+16 ]
= sqrt 25
Goodness, thank you.
You are welcome.
However when in danger or in doubt
SKETCH A PICTURE of it !
If you had done it, you would have seen the right triangle immediately.
