d on the other hand all pairs of realvalues of x and y which satisfy the equation, whenviewed as co-ordinates, conduct us to points on CD;for give to x in the equation any value, say thatrepresented by OX, then the equation gives for y Equations and Loci. 25 the value y = 6- 0X\ which is XP. We say… … travels along the curve, they are nevertheless alwaysconnected by the relation x~ + ij~ = ^9. Hence x- + y- = 49is said to be the equation of this circle, for it is theanalytical representation of the circle in the sense thatthe co-ordinates of every i)oint on the circle are boundby the relation x-…
