#### Answer

$Xmin = -100 $ $ Ymin = -20 $
$Xmax = 100$ $ Ymax = 20$
$Xscl = 10$ $Yscl= 2$

#### Work Step by Step

The $Xscl$ and the $Yscl$ are given below the graph.
We must now count the amount of units to the left and right of the origin and multiply them by the given $Xscl$ to determine $Xmin$ and $Xmax$. Numbers were chosen such that no calculator work is required.
We must now count the amount of units upward and downward from the origin and multiply them by the given $Yscl$ to determine $Ymin$ and $Ymax$.
