Answer: Rotate 180 degrees around point B</h3>
Explanation:
Point A(-3,1) moves to A ' (1,1). The line through these two points is y = 1.
Point C(-3,3) moves to C ' (1, -1). The line through these two points is y = -x
These two lines intersect at point B(-1,1) which is the invariant point, aka fixed point. It is the center of rotation.
Notice how points A, B and A' are collinear (i.e. they are on the same line). The same can be said about points C, B and C'.
Because of these two sets of collinear points, it means we have a 180 degree rotation going on.

Answer:

Step-by-step explanation:
A ball is 10 meters. Since 100 centimeters are in a meter, each ball has 100*10 = 1000 centimeters.
The teacher needs 70 strings each 40 centimeters. The total amount they need is 70*40 = 2800 centimeters.
Since a ball has 1000 centimeters, 2800 centimeters will need 3 balls for a total of 3000 centimeters.
