Line elements at these points with their respective slopes are graphed in Fig. 18-1. Continuing in this manner
we generate the more complete direction field shown in Fig. 18-2. To avoid confusion between line elements asso-
ciated with the differential equation and axis markings, we deleted the axes in Fig. 18-2. The origin is at the center
of the graph.
