6. Let a = H(0,3), 2)0m, where m: y = 3x + 2. Find the algebraic representation of a. Find the image of A(0,3)(2,4)(-1,-2) under a. 7. Show that a homothety, H((01,02),k) has the algebraic representation: x' = ax by + c ly' = (bx + ay) + d where Va+ b2 = |kl. 6. Let a = H(0,3), 2)0m, where m: y = 3x + 2.
