Quadrilateral A B C D has vertices at A negative two comma negative one, B negative four comma negative seven, C negative nine comma negative three and D negative eight comma negative six. It is reflected across the x-axis. What are the new coordinates? Explain.

anonymous · Answer

For all the vertices, the sign of y-coordinate changes. 
For example,
A(-2,-1) will be A'(-2,1) after reflection in x-axis. 
B(-4,-7) will be B'(-4,7)
C(-9,-3) will be C'(-9,3)
D(-8,-6) will be D'(-8,6) 
Reflection does not change the shape or size of the figure. It just flips it over.
