A vertical line that a graph rushes towards but never crosses is a vertical:
AAsymptote
BAmplitude
CAssembly
DAlignment
Answer & Solution
Correct answer: A. Asymptote
1. Near that input the outputs run off to infinity.
2. The graph hugs the line without ever meeting it.
3. That line is a vertical asymptote.
