8-72.

Examine the system of equations below.

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

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.

The line $x=0$ is the $y$-axis.

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