Answer:
the equation that has the ordered pair as its solution is;
[tex]y=5x[/tex]
E
We want to find the equation that has its solution as the given ordered pair:
[tex](3,15)[/tex]
Let us substitute the value of the x into each equation and see which one gives the correct value of y;
[tex]\begin{gathered} y=5x=5(3)=15\text{ (3,15)} \\ y=3x=3(3)=9\text{ (3,9)} \\ y=\frac{1}{3}x=\frac{1}{3}(3)=1\text{ (3,1)} \\ y=\frac{1}{5}x=\frac{1}{5}(3)=\frac{3}{5}\text{ (3,}\frac{3}{5}) \end{gathered}[/tex]
Therefore, from the given options, the equation that has the ordered pair as its solution is;
[tex]y=5x[/tex]
