$(2, 3)$ $(2,3)$

Explanation:

$we have y \propto x$ $"we have " ypropx$

$\Rightarrow y = k x \leftarrow direct variation$ $rArry=kxlarrcolor(red)" direct variation"$

$to find k the constant of variation use (10, 15)$ $"to find k the constant of variation use " (10,15)$

$y = k x \Rightarrow k = \frac{y}{x} = \frac{15}{10} = \frac{3}{2}$ $y=kxrArrk=y/x=15/10=3/2$

$\Rightarrow y = \frac{3}{2} x \leftarrow is the equation$ $rArry=3/2xlarrcolor(red)" is the equation"$

$x = 2 \Rightarrow y = \frac{3}{2} \times 2 = 3$ $x=2rArry=3/2xx2=3$

$\Rightarrow missing value = (2, 3)$ $rArr" missing value " =(2,3)$
