## Text Solution

Steps:

\begin{align}5x - y &= 5\\\Rightarrow \quad y &= 5x - 5\end{align}

The solution table will be as follows.

 $$x$$ $$0$$ $$2$$ $$y$$ $$-5$$ $$5$$

\begin{align}3x - y &= 3\\ \Rightarrow \quad y &= 3x - 3\end{align}

The solution table will be as follows.

 $$x$$ $$0$$ $$2$$ $$y$$ $$-3$$ $$3$$

The graphical representation of these lines will be as follows. It can be observed that the required triangle is $$ABC$$ formed by these lines and $$y-$$axis.

The coordinates of vertices are $$A( 1, 0),\; B (0, - 3),\; C (0, - 5)$$.
