When you reflect something over the line x=y, you just switch the x and y coordinates.
The reflection of the vertical line x = -3 over y = x is a horizontal line,
y = -3

You basically reflect each point on the line x=y (ex. 1=1, 2=2...etc. a diagonal line)
Then you reflect it on all of those other lines too. Like if the point was A=(2,0) then the reflection on x=-3 would be A'=(-8,0)

When points (a,b) on the x-y number plane are reflected in the line y = x the resultant reflection has points (b,a) ie the coordinates in the ordered pair swap positions.

So (-3, 0) --> (0, -3) (ie x = -3 goes to y = -3)
(2, 0) --> (0, 2). and (ie x = 2 goes to y = 2)
(0, -3) --> (-3, 0) (ie y = -3 goes to x = -3)

if x = y then the line will go diagonally accross the axis at 45 degrees -

if you have a cross on your image then start at point y-3/x-3 and then draw the line up to x2/y2 = then draw the image the same distance away on the other side

if you want the reflective of x=y, you will need y=-x

I don't even understand the question.
