Examine the system of equations below. 

$\begin{array} 5x−2y=4\\x=0\end{array}$

1. Before solving this system, Danielle noticed that the point of intersection is also the y-intercept of $5x−2y=4$. Explain how she knows this.

   Hint (a):

   The line $x=0$ is the $y$-axis.

2. Find the point of intersection of the two rules above.
