We know that the rule for rotation of 
is given by :-
, where (x,y) is the point of pre-image and (-y,x) is a point of image.
The given point of pre-image : A(8,2)
Then after rotation of , we have the image point as :-
Hence, the image point of A(8,2) is (-2,8) .
Answer:
B. 10 1/2 feet
Step-by-step explanation:
We are told that she taped 7 boxes.
We are also told that she uses 1 1/2 feet of tape to close each box.
Therefore, the length of tape she will need to use for the 7 boxes will be the product of 7 boxes and 1 1/2 feet of tape per box:
L = 1 1/2 * 7 = 3/2 * 7 = 21/2 = 10 1/2 feet.
She will need to use 10 1/2 feet of tape.
