# Math Help - Coordinates

1. ## Coordinates

Please help, a little confused over this one, i'm acutally working on congruent parts, and this one seem a bit different that the ones i've been doing

Determine the coordinates of the point three-fourths of the way from A(-9,3) and (-1,-7)?

Thanks

Consider the x-coordinates first.
From -9 to -1 are 8 steps. Therefore 3/4 of the way is 6 steps. -9+6=-3.
Then do a similar process for the y-coordinates.

Thanks for the info, but i got that one, i'm having problems with the y-coordinates, i'm supposed to be using absolute value, and it just doesn't seem to be working out.

3 to -7 means -10 steps
3/4 of the way is -7.5 steps.
3-7.5 = -4.5
What's absolute values got to do with it???

I'm doing division of line segments, and was told to use absolute values, can't do that in here, so i'm trying to figure out why, i kept coming up with a positive number which can't work.

Thanks so much for your help
