We can often find enough of these points toshow the general form of the locus ; for we must bear in mindthat a curve drawn at random (as in the figure) is not the locusof any equation. The equation expresses some /aw… … be a line drawn at ran-dom. Hence the generalform of the curve will berepresented by the posi-tions of points upon it,chosen at reasonable in-tervals. This method of deter-mining a curve by pointsis called//(?///;;^ the curve.Let us plot the curve whose equation \s x — y -\- 2 = o.If we choose any…
