Quick question... My teachers homework answers say the negative reciprocal (NR) of 0/8 is -1 via this process: =0 / 8 =0/1 NR =-1 I mean, 0/8 is equal to 0/1, but I got this: =0/8 =0 NR = 0 I'm pretty sure I'm right, but my teachers answers aren't usually wrong. Who's right here? |

I'm pretty sure the opposite of zero is infinity, in regards to slope: m = 1/0 NR = 0/1 Think about it. if you have a flat line on a graph, what is the opposite of that? |

The negative reciprocal of a/b = -b/a. Therefore the reciprocal of 0/8 = -1/0 = undefined. It's a vertical line. |

-_- Not sure why I thought the opposite of 0 was 0. Makes sense now, thanks guys! |
