Reflection of point (x ,y) about x axis is given by (x,-y) and about y axis is given by (-x,y) .treat the line as plane mirror about which you have to find out point reflection .thus Q is (5 ,-6) and R is(-5,6)..
Answer:
21
Step-by-step explanation:
54.8/2.6=21.0769230769
21.0769230769 rounded would be 21
On the first place we need to write the value of x, on the second place - the value of y.
{(-3,3), (0,0), (2,-2)}.
So, the answer is A.
