srry bout the delay folks i was havin a bit too much fun with my blow-dart gun XD

OpenStudy (secret-ninja):

Well, to reflect it over the x axis, you just take it and literally flip it, using the opposite points. If D is (-1,1) then it becomes (-1,-1). The same goes for the rest of the points and when it is flipped over the y axis.

OpenStudy (anonymous):

i know that much XD

OpenStudy (secret-ninja):

If the letter you want is A, and it is in the point (-4,1) and you flip it over the x axis, what do you get?

OpenStudy (anonymous):

(-4,-1) right?

OpenStudy (igreen):

Point A is located at (-4, 1). Reflection over y-axis: (-x, y) Reflection over x-axis: (x, -y) Rotation of \(180^ \sf o\): (-x, -y)

OpenStudy (igreen):

Nope. @WhiteFangIII

OpenStudy (secret-ninja):

Yep. You just have to do the same thing, but on the y. so what would you get?

OpenStudy (anonymous):

(4,-1)

OpenStudy (anonymous):
