Question

Which transformation does this rule describe?
(x,y)-->(-x,y)
options ;
a-reflection over the y-axis
b-rotation of 90 degrees counterclockwise
c-translation left 1 unit
d-reflection over the x-axis

Answer 1

It is A.) Since the x coordinate will change, but not the y coordinate, take (x,y) and reflect

across the y axis and you have (-x,y)
