Abstract

The three lines 1i = aix +biy+ ci = 0, i = 1, 2, 3, meet in a point if the third order determinant │a1b2c3│ is zero. This is a necessary and sufficient condition if it is assumed that three parallel lines meet in a point. This paper is concerned with the answer to the question: How many points can be associated with a given third order determinant which is zero if equations of lines are formed by using the elements of the determinant as the coefficients?
