Answer:

(b, a)

Step-by-step explanation:

Example if D was (3, 2) and reflects across y = x, D' will be (2, 3)

MrRoyal

The coordinates of the image of D is (b,a)

How to determine the coordinates of the image of D?

The point D is given as:

D = (a,b)

The rule of reflection across the line y = x is

(x,y) -> (y,x)

So, we have:

(a,b) -> (b,a)

Hence, the coordinates of the image of D is (b,a)
