If point R was at (-5 , -5) And is now at R' (-11 , -11) How did it get there? From the x-coordinate, it moved...? And from the y-coordinate, it moved...?

OpenStudy (here_to_help15):

-6 units to the left and -6 units up

OpenStudy (johnweldon1993):

Well just try and think in terms of '+' and '-' |dw:1433373922536:dw| It looks like we go down 6 units....and also to the left 6 units right? So it looks like our rule is to be (x - 6, y - 6) right?

OpenStudy (here_to_help15):

Yea and oops i meant down not up

OpenStudy (johnweldon1993):

Not a problem :) So now we just apply that same translation rule to the U coordinate given \[\large U = (U_x , U_y) = (-5, 1)\] \[\large U' = (U_x - 6, U_y - 6) = ?\]

OpenStudy (here_to_help15):

? lost me there bud

OpenStudy (johnweldon1993):

So we need to find where U will be after the translation right? We found out that the translation rule = (x-6, y-6) Meaning, with all of our points BEFORE the translation...we must apply this rule that we subtract 6 from both the 'x' and the 'y' coordinate So since the coordinate for U is (-5, 1) After the translation we will have a U' of \(\large (-5 - 6, 1 - 6) = (?,?)\)

OpenStudy (here_to_help15):

-11,-5

OpenStudy (johnweldon1993):

Correct indeed...so it looks like choice B is correct there

OpenStudy (here_to_help15):

:D next one :)

OpenStudy (johnweldon1993):

So now, for the second one...remember how we found out that last translation rule? We said x - 6 meant going 6 to the LEFT from the original point and y - 6 meant going 6 DOWN from the original point? What would (x - 7, y - 7) mean?

OpenStudy (here_to_help15):

lol that was easy :)

OpenStudy (here_to_help15):

A right @johnweldon1993

OpenStudy (johnweldon1993):

Dont ask me tell me :P lol

OpenStudy (here_to_help15):

lol

OpenStudy (here_to_help15):

My teacher would say "Are you asking me, or telling me. "

OpenStudy (here_to_help15):

"Are you asking me, or telling me? " *

OpenStudy (johnweldon1993):

XD I've been tutoring for like 4 years so I've gotten used to saying that too XD

OpenStudy (here_to_help15):

5 is A

OpenStudy (here_to_help15):

lol

OpenStudy (anonymous):

lol

OpenStudy (johnweldon1993):

Haha, but okay on to the last one! |dw:1433374687576:dw| whats the rule?

OpenStudy (here_to_help15):

A was wrong?

OpenStudy (here_to_help15):

I thought \[ - \] meant to go down ?

OpenStudy (johnweldon1993):

It does indeed mean go down...however, read the question one more time Needs to go 5 rows down "y-coordinate" and 3 seats to the right "x-coordinate"
