Answer 12

Hint
X axis reflection: (x,y) --> (x, -y)
Y axis reflection: (x,y) --> (-x,y)
Y= X reflection: (x,y) --> (y,x)

Answer 13

so its C? I still don't know..

Answer 14

or D?

Answer 15

Take point (1,3) and apply D transfigurations
Y= x reflection would change it to (3,1)
X axis would change it to (3,-1) Y= x would change it to (-1,3) Y axis would change it to (1,3) Which made it back to the original so yeah D

Answer 16

Oh so y=x, x-axis, y=x, y-axis is right?

Answer 17

I meant to type transformations

Answer 18
