To provide you with a more accurate answer, I'd need a bit more context. Generally, when discussing intercepts in mathematics, we often refer to the x-intercept and y-intercept of a line or a curve on a graph. Viable solutions could mean various things depending on the context you are referring to, such as solutions to equations, points of intersection, or feasible solutions in optimization problems.
If you meant to provide a list of options, please share those options so that I can analyze them and determine which ones can utilize both intercepts effectively.
