Did i draw the line x=2 correctly? and how do i do b? what does it mean by reflect it in line x=2? plz plz plz !

Yes your x=2 line is correct

Currently what the artist drew are at their points A B C and D.
You have to reflect this across the y axis (which would make it go into the line x=2)
After you reflect it across the y axis, you will label the new coordinates A' B' C' and D'
and write the coordinates down as well
