1. Determine which ordered pair is a solution of y = x*2–2.

A: (–2, 6)
B: (5, 21)
C: (–1, –1)
D: (–5, 24)

2. Does the figure below have rotational symmetry?

Yes; it can be rotated 360° or less and match the original figure.
Yes; it can be rotated 180° or less and match the original figure.
No; it does not match the original figure after any rotation of 180° or less.
No; it does not match the original figure after any rotation of 360° or less.

for number one plug in each pair and see which one makes it true.

anonymous · Answer

So it would be -1 -1? That's the first answer I got.

anonymous · Answer

yupp!

anonymous · Answer

Thanks!

anonymous · Answer

for number 2,  the pattern is continual so yes you can rotate it. if you rotate it, 90, 180, 270, or 360, it will look like the original :D

anonymous · Answer

Oh okay, I was having trouble with the second one, I turned my head and it didn't look like the same shape to me.

anonymous · Answer

well, what you could do, is screenshot it and put it into word or something and rotate it 90 degrees

anonymous · Answer

I'll do just that. Thanks again!
