<u>Answer:</u>

The correct answer option is b = -a.

<u>Step-by-step explanation:</u>

We know that a number b is located the same distance from 0 as another number, a, but in the opposite direction.

So, The equation will be b = -a which is the same as writing b = -1 * a.

Here, the negative sign with the 'a' will change it from positive to negative, or vice versa.

Recall how,

negative times positive is negative; and

negative times negative is positive.
