Where would the point $\left(11, −18\right)$ be after each transformation described below?  

1. Reflect $\left(11, −18\right)$ across the $x$-axis, and then reflect that point across the $y$-axis.

   Hint (a):

   Think of the axis as a mirror that reflects an image of the point to the other side.

2. Translate $\left(11, −18\right)$ $5$ units to the right and $3$ units down.
