Hello OneidaFL
77.0/-7.77
I'm not sure why you should think that the answer may be undefined. Just use the ordinary rules of arithmetic:
\(\displaystyle \frac{77}{-7.77}=-\frac{77}{7.77}\) (positive divided by negative equals negative)
\(\displaystyle =-9.9099\), correct to 4 d.p.

Yes, undefined means that there are no answers. When you have an undefined slope, it means the slope is infinite. Infinity is an undefined term. So is negative infinity. If your answer is either of these, then the problem is undefined.

This specific problem has an answer.
