Question

Triangle XYZ is shown on the coordinate plane below.

If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?

(1, -5)

(1, -3)

(1, 3)

(1, 5)

Answer 1

It will be (1,5) Its simple,
First draw the mirror at y=1 which will be a line parallel to x axis. Now the point is 4 unitis below the mirror. So it will be exactly 4 units above the mirror in a straight line..

Answer 2

thank you could you help me with another one please

Answer 3

sure

Answer 4

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
