Answer
Xmin = -400
Xmax = 600
Xscl = 100
Ymin = -600
Ymax = 1000
Yscl = 200
Work Step by Step
We are given the Xscl and Yscl, respectively 100 and 200. There are four tick marks to the left of the origin, so $4*100 = 400$. There are six tick marks to the right of the origin, so $6*100 = 600$. There are three tick marks under the origin, so $3*200 = 600$. There are five tick marks above the origin, so $5*200 =1000$.
