Abscissa and ordinate a parametric equation. Used in this way, the abscissa can be thought of as a coordinate-geometry analog to the independent variable in a mathematical model or experiment (with any ordinates filling a role analogous to dependent variables). Abscissa and ordinate In mathematics, the abscissa (; plural "abscissae" or "abscissæ" or "abscissas") and the ordinate are respectively the first and second coordinate of a point in a coordinate system. The abscissa of a point is the signed measure of its projection on the primary axis, whose absolute value is the distance between the projection and the origin of the axis, and
Graph equation solutions of the graph equation "L"("K") = "T"("K") and "G" = "K", and "H" = "K" are the solutions of the graph equation "L"("K") = "T"("K"). Note that "T"("K") is a 4-regular graph on 6 vertices. Graph equation In graph theory, Graph equations are equations in which the unknowns are graphs. One of the central questions of graph theory concerns the notion of isomorphism. We ask: When are two graphs the same (i.e., graph isomorphism)? The graphs in question may be expressed differently in terms of graph equations. What are the graphs (solutions) "G" and "H" such that the line
