"left 3 " means subtract 3 from each x coordinate
"up 5" means add 5 to each y coordinate
OpenStudy (anonymous):
theres not picture tho
jimthompson5910 (jim_thompson5910):
are any ordered pairs given?
OpenStudy (anonymous):
no, this homeschool website is like set up to make me fail there's no information
jimthompson5910 (jim_thompson5910):

yes
jimthompson5910 (jim_thompson5910):
that tells us that the point A is (1,1)
OpenStudy (anonymous):
ok
jimthompson5910 (jim_thompson5910):
they want us to move point A "left 3 and up 5"
jimthompson5910 (jim_thompson5910):
where will point A end up?

left 3 and up 5
jimthompson5910 (jim_thompson5910):
so can you draw or graph point A?
jimthompson5910 (jim_thompson5910):
in other words, can you graph (1,1)?
OpenStudy (anonymous):
kay hold on
jimthompson5910 (jim_thompson5910):

i got lost
jimthompson5910 (jim_thompson5910):
alright, take a look at the attached
jimthompson5910 (jim_thompson5910):
Now we want to move that point A to the left 3 and up 5
OpenStudy (anonymous):
okay
jimthompson5910 (jim_thompson5910):
where does it end up?

(4,5) ?
jimthompson5910 (jim_thompson5910):
subtract 3 from the x coordinate to get: 1 - 3 = -2
then add 5 to the y coordinate to get: 1+5 = 6
So A moves to the point (-2, 6)
OpenStudy (anonymous):
oh :p
jimthompson5910 (jim_thompson5910):
you do this for every point listed
OpenStudy (anonymous):
okay :) thanks
