jimthompson5910 (jim_thompson5910):

hint: An ordered pair is another name for "point"

jimthompson5910 (jim_thompson5910):

by "point" I mean a point on a coordinate grid

OpenStudy (caitlinnr14):

im still confused

jimthompson5910 (jim_thompson5910):

examples of ordered pairs: (2, 3), (6, 7), (11, 22) they are just points on a 2D grid

OpenStudy (caitlinnr14):

... im not getting what you are trying to say

jimthompson5910 (jim_thompson5910):

what do (2, 3), (6, 7), and (11, 22) all have in common?

OpenStudy (caitlinnr14):

ummm

jimthompson5910 (jim_thompson5910):

what's one similarity

OpenStudy (caitlinnr14):

im not getting this

jimthompson5910 (jim_thompson5910):

I'll list one similarity and hopefully that will get you thinking in the right direction

jimthompson5910 (jim_thompson5910):

they all are surrounded by parenthesis

jimthompson5910 (jim_thompson5910):

what's another similarity?

OpenStudy (caitlinnr14):

they are all numbers?

jimthompson5910 (jim_thompson5910):

good, focus on something like (2,3) they are a ____ of numbers

OpenStudy (caitlinnr14):

set?

jimthompson5910 (jim_thompson5910):

not a wrong answer, but not what I'm looking for

jimthompson5910 (jim_thompson5910):

when two things come together they form a _____ hint: starts with a p

OpenStudy (caitlinnr14):

pair?

jimthompson5910 (jim_thompson5910):

they form a pair, correct

jimthompson5910 (jim_thompson5910):

so (2,3) is a pair...an ordered pair because you can't flip them (or else you change the point entirely)

OpenStudy (caitlinnr14):

ok

jimthompson5910 (jim_thompson5910):

in general, you can replace the 2 with x and the 3 with y (2,3) is an example (x,y) is the more general form

OpenStudy (caitlinnr14):

ok

jimthompson5910 (jim_thompson5910):

see the answer now?

OpenStudy (caitlinnr14):

x and y values written in the form (x, y)?

OpenStudy (caitlinnr14):

@jim_thompson5910

jimthompson5910 (jim_thompson5910):

correct

OpenStudy (caitlinnr14):

yay and thx for the medal
