[tex]\huge \bf༆ Answer ༄[/tex]
Let's take Two terms x And y, according to graph ;
[tex]{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y \propto x[/tex]phlll
now, let's add a proportionality constant to convert proportionality to equation.
[tex]{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y = kx[/tex]
let's plug the value of x and y from any ordered pair according to graph, I.e (5 , 3)
[tex]{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:3 = 5k[/tex]
[tex]{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:k = \dfrac{3}{5} [/tex]
