Question

Find the points which define the reflection of the figure given by A(2, 2), B(5, 7), and C(8, 5) reflected across y = x.

Answer 1

Please do your best not to post with none of your own work showing.

Do you know how to find an Inverse Function?

Answer 2

No

Answer 3

Too bad. That would have been useful.

Can you reflect (8,0) across the line x = y? Where does it go?

Answer 4

Like before? (8,-0)?

Answer 5

Why would a reflection across x = y be the same as a reflection across the x-axis?

1) "-0" doesn't mean anything.
2) Look at it on a set of coordinate axes and reason it out. Where does it go?

No guessing.

Answer 6

Reflection about y=x, you interchange the coordinates

Answer 7

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

Answer 8

(5,7)->(7,5)

Answer 9

(8,5)-> (5,8)

Answer 10

Ohhhh right, I remember now, y=x you swap the two thanks
