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?

math 
Michael,
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.

math 
keisha,
is it b?

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

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

math 
Michael,
That's the right logic. Good job. :)
