what are the coordinates of the image of vertex f after a reflection across the line y = –x?

a(–1, –3)
b(3, –1)
c(1, 3)
d(–3, 1)

The new co ordinate would be (3,-1)

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
