The rotation (x, y) → (-y, -x)
The translation (x, y) → (x + 4, y - 8)

a reflection across line m
a reflection across the x-axis
a clockwise rotation of 100° about the origin
a clockwise rotation of 144° about the origin
A trapezoid is shown in the coordinate plane. Which of the following gives the line or lines of symmetry about which the trapezoid can be reflected in order to map the trapezoid onto itself?
y = x
x = 4
x = 4 and y = 2
x = 0 and y = 0
Which correctly describes the two transformations that were used to create the image on the graph?
Reflection over the y-axia and a rotation 90o counter clockwise
(x+10, y) and reflection over x-axis
