Answer
$X[-10,110,10]$ by $Y[-10,160,10]$
Work Step by Step
1. Examine the given coordinates, we can find the minimum and maximum of each direction as $X, 0, 100$ and $Y, 0, 150$
2. Set scale=10 and the window 10 unit larger each direction to cover the above numbers, we can get the viewing window as $X[-10,110,10]$ by $Y[-10,160,10]$ where the first number in the bracket represents the minimum value, the second number the maximum value, and the last number the scale.
