| Question 54353:  Hi I am having really bad trouble with this problem and i have used all the posible solutions i can think of. I am trying to help my daughter and i have not been in algebra in 23 years and i do not remember a thing.
 So if you could please give me the answer to this question in great deatail so maybe i can help her.
 Here is the Question:
 Find the coordinates of the vertices of each figure after the givin transformation is performed.
 Triangle RST with R(-2,4),S(2,0),T(.1,.1) reflected over the y axis

You can put this solution on YOUR website! Find the coordinates of the vertices of each figure after the givin transformation is performed. Triangle RST with R(-2,4),S(2,0),T(.1,.1) reflected over the y axis
 ---------------
 If a point (a,b) is reflected in the y-axis it become (-a,b)
 So your points become:
 (2,4), (-2,0), (-0.1,0.1)

You can put this solution on YOUR website! When you reflect something about the y axis, you want the point to have the same heighth, but be equally far on the other side of the y-axis.  We can do that by changing the sign of x and keeping y the same.(x,y) would be (-x,y) and (-x,y) would be (x,y) :
 R(-2,4) would be (2,4)
 S(2,0) would be (-2,0)
 T(.1,.1) would be (-.1,.1)
 :Plot the points and see that it's the same triangle flipped on it's side about the y-axis.  I can't graph triangles on this or I'd show you.
 Hope that helps.
