Answer
$X[-3,7,1]$ by $Y[-4,9,1]$
Work Step by Step
1. Examine the given coordinates, we can find the minimum and maximum of each direction as $X: min=-2 , max=6$ and $Y: min=-3, max=8$
2. Set scale=1 and the windows to cover the above numbers, we can use the viewing window as $X[-3,7,1]$ by $Y[-4,9,1]$ where the first number in the bracket represents the minimum value, the second number the maximum value, and the third number the scale in each brackets.
