Plz Help!!! thanks soo much..?
it says: find (a) PQ to the nearest tenth and (b) the coordinates of the midpoint pg line segment PQ…………..then for the actual problem it says P (-4, -5) , Q (-1, 1)
please help me im soo lost. like i dont know what im suppose to do but i think one of the answers is (-2.5, -2)
thanks soo much in advance.

The distance formula (for distance between two points) is:
Sq. root of ( [(x1 – x2)^2] + [(y1-y2)^2])
Sq. root of ( [(-4 – -1)^2] + [(-5 – 1)^2])
Sq. root of ( -3^2 + -6^2)
Sq. root of (9 + 36)
Sq. root of 45
So PQ is the square root of 45 to the nearest 10th.
And you’re right about b.
midpoint equals (x1+x2)/2, (y1+y2)/2
Hope it was clear enough for you to read (stupid limited keyboard) and I hope I could help. Good luck!

use the gap formula. d=sqrt ((x-x)squared+(y-y)squared) a) i’ve got been given 7.one million contraptions. then use (x+x)/2,(y+y)/2 b) i’ve got been given (2.5,2.5). this is likewise what you acquire! YEAH!! *air extreme-5* 🙂 goo success! desire I helped!
