Question

Please Help!!!!! I WILL FAN and MEDAL!!!!!!


The vertices of a triangle are p(-7, -4) q(-7, -8) and r(3, -3). Name the vertices of of the image reflected across the line y = x.

a) p(4, 7); q(8, 7); r(3, -3)
b) p(4, -7); q(8, -7); r(3, 3)
c) p(-4, -7); q(-8, -7); r(-3, 3)
d) p(-4, 7); q(-8, 7); r(-3, -3)

Answer 1

I would go with c not really sure tho

Answer 2

Oh the word reflected is in it. That means it's mirrored i.e in reverse if I'm correct.

Answer 3

yes

Answer 4

We can rule out C, because that's not a mirrored image of the triangle. (-4, -7) is not a mirror of (-7, -4) because the X and Y are on a completely different level.

Answer 5

ok

Answer 6

I was thinking A but I'm not sure

Answer 7

(-4,7) can't be a reflection either. which is D. (-4, -7) cannot be reflected to (-4,7) it's not logical.

Answer 8

I'm leaning onto A as well. Because C and D is incorrect.

Answer 9

Ok, well thank you! :)

Answer 10

It was actually C @Jamal5337

Answer 11

Really? Sorry about that! I'm still going over the math right now!

Answer 12

A reflection would make the image upside down on the line

Answer 13

Please note that when you perform a reflection about the y=x line, you have to change x---> y
and y---> x

Answer 14

namely the point (-7, -4) is mapped into point (-4, -7)

Answer 15

*Face To Desk* Forgot about that

Answer 16

*Face To Desk* Forgot about that

Answer 17

I was thinking about flipping it from left-->right, not up-->down
