a. y = -30 ... x = 15 y = 60 ... x = ? ------------------------------- -30 * x = 15 * 60 x = - 15 * 60 / 30 x = -30 b. y = 8 ... x = 3 y = ? ... x = 45 ------------------------- 8 * 45 = y * 3 y = 8 * 45 / 3 y = 120 c. x = -6 ... y = ? x = -5 ... y = 15 ------------------------- -6 * 15 = -5 * y y = 6 * 15 / 5 y = 18
