Question #49
MultipleSelect
A'B'C'D' is the image of ABCD. What transformation(s) would result in this image?
ABCD is reflected over the line y = x.
ABCD is dilated about the origin with a scale factor of 1.
ABCD is reflected across the yaxis and then the xaxis.
ABCD is rotated 180° around the origin.
Question #50
MultipleChoice
A circle has a diameter with endpoints (8, 2) and (2, 6).
What is the equation of the circle?
r2 = (x  3)2 + (y + 4)2
r2 = (x  5)2 + (y + 4)2
r2 = (x + 5)2 + (y  4)2
r2 = (x + 3)2 + (y  4)2

Wow,
do you really expect somebody to do this whole assignment for you?
