When documenting your network infrastructure, you are obtaining both hardware data to document your infrastructure's physical structure and software data to document the existence and configuration of the protocols in use on your network.
1. perpendicular-a straight line at right angles to another line. straight line-a line traced by a point traveling in a constant direction; a line of zero curvature; the shortest distance between two points is a straight line.
Sections: Slope-intercept form, Point-slope form, Parallel and perpendicular lines. There is one other consideration for straight-line equations: finding parallel and perpendicular lines. Here is the usual format for the question: 1  Given the line 2x â 3y = 9 and the point (4, â1), find lines through the point that are:his is the parallel line that they asked for. For the perpendicular line, I have to find the perpendicular slope. The reference slope is m = 2/3, and, for the perpendicular slope, I'll flip this slope and change the sign. Then the perpendicular slope is m = â 3/2.
