not a wrong answer, but not what I'm looking for
jimthompson5910 (jim_thompson5910):

jimthompson5910 (jim_thompson5910):
they form a pair, correct
jimthompson5910 (jim_thompson5910):

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):

OpenStudy (caitlinnr14):
