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 x-axis. 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.

• math -

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. :)
