You would need to know the cost of the box of 20, then you would divide the total cost by the number of pencils in the box. This would give you the cost of one pencil - which is the unit cost.

Divide the total cost by the number of pencils:
10 / 20 = 0.50 - This means each pencil cost 50 cents, so the unit cost would be 50 cents per pencil.
Point symmetry is a 180 degree rotation around the origin.
It maps (x,y) to (-x,-y).
So (2,6) and (-1,2) map to
(-2,-6) and (1,-2), third choice
