6. Which equation represents a direct linear variation?

 y = x2

y=2/5x

y=1/x

y = x + 3

7. Which is the direct linear variation equation for the relationship?

y varies directly with x and y = 12 when x = 4.

y = 2x + 4

y = 3x

y = x + 8

y = x – 89. Which is the quadratic variation equation for the relationship?

y varies directly with x2 and y = 48 when x = 2.

 y =1/12  x2         

y = 12x2

 y = 1/24 x2

y = 24x211. y varies inversely with x and y = 8 when x = 2.

6. y = (2/5)x is a direct linear variation

7. y = 3x is a direct linear variation (x = 4, y = 12)

9. y = 12 x^2 varies directly with x^2 and y = 12*2^2 = 12*4 = 48

11. If y varies inversely with x and y = 8 when x = 2, then y = k/x; 8 = k/2, and k = 16.

The answer is y = 16/x.
