all y values change sign
that is reflection over x axis
SKETCH IT !!!!
A figure has vertices E(-3, 1), F(1, 1) and G(4, 5). After a transformation, the image of the figure has vertices at E'(-3, -1), F'(1, -1) and G'(4, -5). Identify the transformation.
a) Reflection across the y-axis
b) Reflection across the x-axis
c) Rotation
d) Translation
Is it a rotation?
