U(-2, 6) --> U'(?, ?)

ganeshie8 (ganeshie8):
just add "-2" to x coordinate,
and add "6" to y coordinate
ganeshie8 (ganeshie8):
U(-2, 6) --> U'(-2-2, 6+2)
ganeshie8 (ganeshie8):
simplify

?
OpenStudy (anonymous):
-2 x -2 = 4.
ganeshie8 (ganeshie8):
yes, thats when we multiply,
but when we add -2-2 = -4
OpenStudy (anonymous):
Oh.
ganeshie8 (ganeshie8):
-2*-2 = 4
-2 - 2 = -4
-2 + 2 = 0

But you didn't do an addition sign. :/
ganeshie8 (ganeshie8):
actually to be precise, it should be writte as below :
(-2) + (- 2) = -4
