If the slope of a straight lineand a point on the line are known, the equation of the line isreadily found. Let LK (fig. 65) be… … Fig. 65 This is an equation whichobviously satisfied by the coordi-nates of any point on LK and by those of no other point.Hence it is the equation of LK. If the line is parallel to OX, m — 0, and the equation of theline is ,ON y=yx- (2) If the line is parallel to 0 Y, m = <x, and the equation…
