Step-by-step explanation:
[tex]x \: dirctly \: as \: y \\ [/tex]
[tex]x = ky \\ (k \: is \: constant)[/tex]
compare it as equation 1
putting values
[tex]6 = 7 y[/tex]
[tex] \frac{6}{7} = y[/tex]
[tex]0.8571 = y[/tex]
and now y when x=12 and k is same
from equation 1
[tex]12 = 7y[/tex]
[tex] \frac{12}{7 } = y[/tex]
[tex]1.714 = y[/tex]
