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
Answer:

Step-by-step explanation:
First of all, let's rewrite the first one after dividing both sides by 2.

Now, let's pick one you want to eliminate.
<u>Eliminating x:</u> Let's multiply the first one by 4, the second by 3, and subtract one from the other. Rest is simply solving an equation in one variable

<u>Eliminating y:</u> Let's multiply the first by 5, the second by 2, and add them together. Rest is simply solving an equation in one variable

Answer:B
