Question

Which set of ordered pairs has point symmetry with respect to the origin (0, 0)?

Answer 1

The answer is the second option, which is: $(9, 2), (-9, -2)$

The explanation for this answer is shown below:

By definition, a set of ordered pairs that has point symmetry with respect to the origin $(0,0)$, has the following form: (a,b), (-a,-b). Therefore, as you can see in the options shown in the problem, the only set of ordered pair that has the form mentioned before is: $(9,2), (-9,-2)$
