Pentagon ABCDE and pentagon A'B'C'D'E' are shown on the coordinate plane below. Which two transformations are applied to pentagon ABCDE to create A'B'C'D'E'? translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the y-axis translated according to the rule (x, y) → (x + 2, y + 8) and reflected across the axis translated according to the rule (x, y) → (x + 2, y + 8) and reflected across the y-axis translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the axis

Would you please tell me the coordinates of D and D'? @hang254
D=-3,-5 D'=1,3
We can see that Pentagon is also reflected across y-axis so first we add something and then reflect it , reflection will change the sign of x- coordinate Would you change the sign of x- coordinate of D' and tell me?
-1 @ash2326
good how can you get -1 from -3?
add 2, to -3. -3 + 2= -1
@ash2326
good so it's x+2 and then reflect across y- axis Now, how to get 3 from -5?
-5+8=3. 8
i see it now. "translated according to the rule (x, y) → (x + 2, y + 8) and reflected across the y-axis" Thanks @ash2326
