Question

PLEASE HELP ASAP DONT UNDERSTAND I understand what a reflection is just not how to do this over axis...
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

at the reflection line y=x, n(x,y) becomes n'(y,x)
so x becomes y and y becomes x

Answer 2

Try and solve it yourself, but if you are struggling, in simple terms it means reverse the 2 numbers in the coordinates.

Answer 3

So find the point at (-2,-1)

Answer 4

So O would be -1, -2 correct

Answer 5

Which is O
