(a) Show that if two points. P (P₁. P₂). Q (9₁, 9₂) with Pr. Pz. 9. 19₂ € R the equation of the line through P and Q is of the form then ax+by =c with a, b, CER. (b) Derive from part (c) that if a line has two rational points, it has infinitely many rational points. P and Q have rational coordinates
