The illustration below shows the graph of $y$ as a function of $x$.
**Complete the following sentences based on the graph.**
* Initially, as $x$ increases, $y$ [[☃ dropdown 1]].
* Afterward, the slope of the graph of the function is equal to [[☃ input-number 1]] for all $x$ between $x=3$ and $x=5$.
* The slope of the graph is equal to [[☃ input-number 2]] for $x$ between $x=5$ and $x=9$.
* The greatest value of $y$ is $y=\:$[[☃ input-number 3]], and it occurs when $x=\:$[[☃ input-number 4]].
