Text: Linear graphs are used in mathematics to model many real-life phenomena. A finite linear graph G is a Hausdorff space that is written as the union of finitely many arcs, each pair of which intersect in at most a common end point. The arcs are called the edges of the graph, and the end points of the arcs are called the vertices of the graph. प्रत्येक पराग्राफले परीक्षण हुनेछ।
