For each of the DEs in Problems, tell whether and where you expect vertical asymptotes or oblique

Question:

For each of the DEs in Problems, tell whether and where you expect vertical asymptotes or oblique asymptotes. Use the direction .field to support your case, and state any other arguments. (You are not expected to solve the DEs. but you should sketch direction fields for Problems sufficiently to answer the asymptote question.
a. y' = y2
b. y' = 1/ty
