I'm in the middle of a calculus course (this is not a calculus question per se), studying from the Larson text, and when an answer to a problem is the equation of a line, I solve for Standard form of a line [itex]Ax + By = C[/itex]. I noticed, however, that the Larson textbook frequently terms answers of the equation of a line in the form [itex]Ax + By + C = 0[/itex], which apparently is the General form (based on my searching around on line. This answer is frequently the equation of a line tangent to a given point on a curve, if that is of any interest. What are the advantages of one form over another? Should I be using General when doing calculus for some reason? Thanks!
