## Algebra: A Combined Approach (4th Edition)

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