x varies directly as y x = ky 3 = 2k k = [latex] \frac{3}{2} [/latex]  when x =9 9 = [latex] \frac{3}{2} [/latex]y [latex] \frac{18}{3} [/latex] = y ∴y = 6 please mark as brainliest

If x and y are directly proportional, x = ky When x = 3, y = 2. So 3 = 2k k = 3/2 So x = 3y/2 When x = 9, 9 = 3y/2 18 = 3y y = 6 So when x = 9, y = 6. Please mark my answer as brainliest. Thank You!
