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

Why did you just give us your homework? D:

@dpalnc is a genius ;D

im not its my sister's. she in the hospital im just trying to make sure she ends the year on time :( or else she will fail.

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

6. lalaly

the first one

7. lalaly

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

8. lalaly

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

@rebeccaskell94 its dpainc << with an i not an L

oh! haha Thanks @lalaly!!
