What is the midpoint of (3,4) and (-1,2)?

jimthompson5910 (jim_thompson5910):

What are the x coordinates here

OpenStudy (anonymous):

3 and -1 I believe..

jimthompson5910 (jim_thompson5910):

good, now add them up

OpenStudy (anonymous):

Mmk

jimthompson5910 (jim_thompson5910):

3 plus -1 = ???

OpenStudy (anonymous):

2

jimthompson5910 (jim_thompson5910):

then divide that in half

OpenStudy (anonymous):

Okay so, 1.

jimthompson5910 (jim_thompson5910):

what you just did by adding up the x coordinates and dividing that result by 2 was find the middle point of the x coordinates...this new value (1) is the x coordinate of the midpoint repeat the last two steps but this time, do it on the y coordinates

jimthompson5910 (jim_thompson5910):

so the y coordinates are ???

OpenStudy (anonymous):

4 and 2

jimthompson5910 (jim_thompson5910):

add them up

OpenStudy (anonymous):

6

jimthompson5910 (jim_thompson5910):

then divide by 2

OpenStudy (anonymous):

3

jimthompson5910 (jim_thompson5910):

so the y coordinate of the midpoint is 3

jimthompson5910 (jim_thompson5910):

which means that the midpoint is (1, 3)

OpenStudy (anonymous):

Awesome, thank you very much!
