Which rule describes a reflection in the x axis?
a (x,y)=(y,x)
b (x,y)=(x,y)
c (x,y)=(x,y)
d (x,y)=(x,y)
Reflection means flipping a figure over. So I made a mistake. I think the answer is c. Is this right?

No, the answer is not c. Try drawing a diagram (like a triangle) on a coordinate plane and then flip it over the xaxis. That will help you to visualize what is happening.

is it b?

Please explain your thought process so I know you're not just guessing.

Since reflection means flipping a figure, x can be flipped over as x and y will stay as y.

That's the right logic. Good job. :)
