OpenStudy (ledah):

Okay why don't you try drawing this out on some paper.

OpenStudy (ledah):

The point x is 4,5 currently

OpenStudy (anonymous):

yes

OpenStudy (ledah):

so if its reflected. the point would have a negative and a positive

OpenStudy (ledah):

which would be -4,5

OpenStudy (anonymous):

you got that so easily!!

ganeshie8 (ganeshie8):

hmm

OpenStudy (anonymous):

??

OpenStudy (ledah):

What @ganeshie8

ganeshie8 (ganeshie8):

Ledah is right if the point is reflected along y-axis

ganeshie8 (ganeshie8):

here they are reflecting along a line y=1

OpenStudy (anonymous):

?isn't it

OpenStudy (anonymous):

what does that mean

ganeshie8 (ganeshie8):

ganeshie8 (ganeshie8):

thats the initial point, before reflection right ?

OpenStudy (anonymous):

yes

ganeshie8 (ganeshie8):

lets draw the line y=1, and reflect the point along this line

ganeshie8 (ganeshie8):
