Line $\ell_1$ is horizontal and passes through $(-5,8)$. Line $\ell_2$ is vertical and passes through $(4,-1)$. Find the point of intersection of $\ell_1$ and $\ell_2$.
A horizontal line is the in the form of y=___. Then the line passing through (-5, 8) must be y=8. A vertical line is in the form of x=___. The the line passing through (4, -1) must be x=4. The point of intersection is therefore (4, 8).
