Answer
Xmin: -20
Xmax: 30
Xscl: 5
Ymin: -30
Ymax: 50
Yscl: 10
Work Step by Step
There are four marks between 0 and the minimum x-value (including the minimum x-value). Since Xscl=5, 5(4)=20. So, Xmin=-20.
There are six marks between 0 and the maximum x-value (including the maximum x-value). Since Xscl=5, 5(6)=30. So, Xmax=30.
There are three marks between 0 and the minimum y-value (including the minimum y-value). Since Yscl=10, 10(3)=30. So, Ymin=-30.
There are five marks between 0 and the maximum y-value (including the maximum y-value). Since Yscl=10, 10(5)=50. So, Ymax=50.
