f a straight line. G6 Analytical Geometry. 10. Express by an equation the relation that must hold betweena and b that the point (a, b) may be equally distant from the lines3a; - 4?/ -r 5 = 0 and x^2y -1 — 0. Give two results. 28. It is, of course, only when {a, h) is a point onthe line Ax + By+C^O… … Let Q be the point (a, b), and KL the lineAx + Bij+C=0. Since when P {a, y) is a point on the line, Aa + By + Gvanishes, therefore Aa + Bb + G = Aa + Bh + C- {Aa + By-\-G)= B(h-y). An examination of the sign of {h - y) for differentpositions of (a, h) as Q, Q^, ... , when (r/, y) is P orPj, will…
