A) translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the y-axis B) translated according to the rule (x, y) → (x + 2, Cy + 8) and reflected across the x-axis C) translated according to the rule (x, y) → (x + 2, y + 8) and reflected across the y-axis D) translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis
is the answer C? i am not sure why, but i would like help on this :( and an explanation
@Hero @campbell_st @Loser66 @dan815 @Kainui
can any of you guys please assist me?
pick the point A how far right do it move to get to A'..? then how far up did A move to get to A'?
8 to the right and 8 up ?
its all adding in the options :(
opps miss read the order... moving A 2 right and up 8 puts it at (-3, 6) then reflecting across the y-axis will put it in the correct position A'(3, 6)
do your choice of C seems correct
let me check
no because it gives me (-3,6)
well if you move 1st... that's the order, then reflect in the y-axis C is the correct answer
when you reflect, the point has to be the same perpendicular distance from the line of reflection.
so basically the subtraction sign is the opposite when i reflect it over the y axis?
well my mistake is I didn't read the order of the 2 step transformation. Step 1. translate ... move of slide to a new position. Step 2 reflect... flip across a line... so be moving 2 right and up 8 you can slide the polygon into a position so it can be reflected into its new position.
sorry to confuse ou as you had identified the correct answer... before I started
oh, lol its okay an thank you for the help :) @campbell_st
