two mirror image halves Hey we're in luck The given

shape has several lines of symmetry with shapes cut in

half by a vertical line passing through the origin as

well as a horizontal line right They're passing through the

origin and this vertical line has equation x equals zero

right no matter what Why is x zero and the

horizontal line has the equation Why is zero always forever

Never well the shape could also be cut in half

by a forty five degree angle line going up right

there read y equals x or up and left at

why equals negative x So we've seen that every answer

choice except for why equals one is a line of

symmetry so that's the odd men out And if we

graft that horizontal line why equals one While we'd see

that it doesn't divide the shape into two symmetrical halves

it was more like you know someone just had an

accident with their carving knife or something All right so 00:01:13.162 --> [endTime] that's it we popped
