Question

Quadrilateral LMNO is shown on the coordinate plane below.



If quadrilateral L'M'N'O' represents the reflection of quadrilateral LMNO across the line y = x, which point is at the ordered pair (-1, -2)?

L'

M'

N'

O'

Answer 1

if you're reflecting over the line y=x, then the x and y coordinates just switches....

Answer 2

So would it be M?

Answer 3

in other words, (x, y) will be (y,x)

Answer 4

nope

Answer 5

(-1, -2) switches to (-2, -1)

Answer 6

what point is that?

Answer 7

O?

Answer 8

O has coordinates (-2, -1) so O' has coordinates switched... (-1, -2)

Answer 9

so O is the answer

Answer 10

yes...:)
