What type of transformation happened from (x,y) –> (-x,y)?
A.Rotation 90*
B.Reflection over the y-axis
C.Translation left 1
D.Reflection over the x-axis


  1. Answer:
    Step-by-step explanation:
    This is a reflection over the y-axis. The x value is changing sign while the y value is staying the same. The general rule for a reflection over the y axis is  (x,y) –> (-x,y), and similarly for a reflection over the x axis is (x,y) –> (x,-y). When you reflect a point over an axis, you flip the sign of the opposite value.
