How are the coordinates of a new point found if the point is reflected through the x-axis? How are the coordinates of a new point found if the point is reflected through the y-axis?

Question

anonymous · Answer

reflection in x - axis: multiply y coordinates by -1

reflection in y - axis: divide x coordinates by -1

anonymous · Answer

reflect through origin-> take the opposite of both x and y 
reflect thru y=x -> switch x and y around 
following that first rule, the third answer would be the origin. 
B' you just make x the opposite (1, -4). B'' you make y the opposite: 
(1, 4) so b and b'' are just reflected across the origin!
