Question

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

(9, 2), (-9, 2)
(9, 2), (-9, -2)
(9, 2), (9, -2)
(9, 2), (2, 9)

Answer 1

(9,2) (-9,-2)

Explanation:

Answer 2

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)`
