    3. y varies inversely as three times x. When x = 3, y = 4. What is the value of x when y = 2? (2 points) 3 6 9 12 4. What is the x– intercept of 5x – 2y = 10? (2 points) (2, 0) (–2, 0) (5, 0) (–5, 0) 5. What is the equation of a vertical line passing through (–4, –3)? (2 points) x = –4 y = –4 x = –3 y = –3

    \[y=\frac{k}{3x}\]when x=3 and y=4\[4=\frac{k}{9}\] so k=36 when y=2\[2=\frac{36}{3x}\]\[6x=36 --> x=6\]

    for the second one x intercept is when y=0 5x=10 x=2 so its (2,0)

    for the third one since its a vertical line then the equation is x=-4
