$y = \frac{x}{6}$ $y=x/6$

$y = \frac{4}{3}$ $y=4/3$

$y$ $y$ varies directly with $x$ $x$

$\Rightarrow y α x$ $=>y " "alpha" "x$

$\Rightarrow y = k x$ $=>y=kx$

$k =$ $k=" "$ constant of proportionality

$x = 24, y = 4$ $x=24,y=4$

$4 = 24 \times k$ $4=24xxk$

$k = \frac{1}{6}$ $k=1/6$

$:.y=x/6$

$y=8/6=4/3$
