Translate trapezoid ABCD left 3 and up 5. What are the ordered pairs of the vertices of the image?

jimthompson5910 (jim_thompson5910):

"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):

hmm that's unfortunate, can you take a screenshot of the whole problem and show me?

OpenStudy (anonymous):

ya

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

A is the point (1,1) agreed?

OpenStudy (anonymous):

i think so

jimthompson5910 (jim_thompson5910):

do you see where it says A(1,1)?

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

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):

alright

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

(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

jimthompson5910 (jim_thompson5910):

sure thing
