Write the notation of point (x,y) after it moves 3 spots to the left and 7 spots up.
(x-3,y+7)
300
The point is reflected according to the rule:
(x, y) -> (-x, y). Over what line was the point reflected?
The line is y-axis.
300
Write the notation of point (x,y) after it rotates 90º clockwise.

What is the difference between congruent and similar figures?
Congruent figures have the same shape and size. Similar figures have the same shape but not necessarily the same size.
