That is incorrect.

SkilerLuke:

how?

Amylebearden:

idk how to do this im new to this

prettydevil45:

i,am confused

ramen:

If you were to look at this graph, do you think that it could just be flipped over to fall on top of the other shape?

ramen:

And if so, would it be over the x axis or y axis?

prettydevil45:

y xis

ramen:

If you flipped the bottom triangle over the y axis, would it fall on top of the other triangle?

prettydevil45:

yes

ramen:

I'll draw a pic

ramen:

The bottom triangle was reflected over the y axis. When that happens, is it on top of the other triangle or no?

prettydevil45:

yes

ramen:

|dw:1611160824042:dw| The shaded triangles are the same triangle but it is just a representation of the it being reflected over the y axis. Now think again, is the shaded triangle on top of the not shaded triangle on top?

prettydevil45:

whatjust give me the answer

ramen:

Bro I can't give you the direct answer. But I'll just say that the answer isn't over the y axis because if that were the case, both triangles would be on top of each other. It isn't center or rotation because we are talking about reflections for this problem. Even if it were to be rotated, it would need to be reflected for both triangles to fit on top of each other. This leaves what answer?
