Kal is decorating the outside edge of a square bulletin board. He needs to know the side length of the bulletin board. The area
of the bulletin board is n square feet.
Which expression shows the side length, in feet, of the bulletin board?
Hint: Formula for area= s^2
Recall the inverse operation that would reverse a number squared.

ANSWER
T(-2,1)
EXPLANATION
Let T(a,b) be the coordinates.
When this point is rotated 90° counterclockwise about the origin,
Then,
If this point is then translated using the rule;
then,
It was given that, T"(-2,5)
This implies that,
-b-1=-2
-b=-2+1
-b=-1
b=1
a+7=5
a=5-7
a=-2
Therefore the coordinates of T are:
(-2,1)
