I would say 
a - yes
b - no
c - no
Now see you agree

btaylor · Answer

a) no, but almost all can. vertical lines are simply x=#, which isn't slope-intercept because there is no slope to a vertical line.
b) no. Horizontal (y=#) and Vertical (x=#) lines have only 1 intercept.
c) usually not. But an equation like$$f(x)=\frac{x^2}{x}$$ would have a hole at the normal y-intercept, so there is no intercept. But, based on the other questions, You are looking at simple lines. So the answer is no.
