WebSystem Graph: The oriented linear graph model of a system. Connected Graph A system graph in which a path exists between all pairs of nodes. A path is said to exist if the node pair is joined by a series of branches. Figure 1 shows a connected graph along with a system graph which is not connected. System WebTo find the linear equation you need to know the slope and the y-intercept of the line. To find the slope use the formula m = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line. The y-intercept is the point at which x=0.
