Choice C. (-3,2)

To get this answer, you first reflect (2,3) over the line y = x. This will have you swap x and y coordinates. So we go from (2,3) to (3,2).

Now reflect over the y axis. We simply change the sign of the x coordinate from positive to negative. The y coordinate stays the same. We go from (3,2) to (-3,2)

The chain of points is

(2,3) --> (3,2) --> (-3,2)

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
