phi · Answer

do you know which axis is the y-axis ?

anonymous · Answer

yes

phi · Answer

"reflect about the y-axis" means
put you finger or pencil on a point.  count how many "steps" to get to the y-axis.
then *count that same number* more and make a mark on the graph.
can you do that for point A?

anonymous · Answer

yeah, but i want you to check my answer...hold on

anonymous · Answer

3 steps??? im not sure i did it right @phi

phi · Answer

the y-axis goes up and down.  You put your finger on point A and *move to the left* to get to the y-axis

anonymous · Answer

what would it be then?

anonymous · Answer

I just need someone to give me the answer with an explanation of how they got the answer

phi · Answer

are you saying you can't put your finger on the A, and count how many steps to the left to get to the y-axis ?
