Question

Kite ABCD is reflected over the line y = x. What rule shows the input and output of the reflection, and what is the new coordinate of A'?
(x,y)→(y,x); A' is at (2, −7)
(x,y)→(−x,y); A' is at (7, 2)
(x,y)→(−x,−y); A' is at (7, −2)
(x,y)→(y,−x); A' is at (2, 7)

Answer 1

Answer:

(x,y)→(y,x); A' is at (2, −7)

Step-by-step explanation:

Answer 2

The answer:

according to the image the coordinates of pre image are:

A(-7, 2), B(-5, 3) C(-2, 2) and D(-5, 1)

Kite ABCD is reflected over the line y = x, the main rule to find the coordinates of the images is  (y, x)

for example if A(-7, 2) the image  A' is A'(2, -7)

the answer is (x,y)→(y,x); A' is at (2, −7)
