The slope of a line whose inclination is ninety degrees is:

ANot defined
BEqual to one
CEqual to two
DEqual to zero
Answer & Solution
Correct answer: A. Not defined
1. Slope is the tangent of the inclination. 2. The tangent of ninety degrees has no finite value. 3. So the slope of such a line is not defined. _Source: syllabus Mathematics, Chapter 10, Straight Lines._
