Xmin: -10 Xmax: 10 Xscl: 1 Ymin: -30 Ymax: 30 Yscl: 3

Since Xscl=1, and there are ten marks between zero and the maximum x-value, and zero and the minimum x-value, 10(1)=10. Therefore, Xmax =10 and Xmin = -10. Since Yscl=3, and there are ten marks between zero and the maximum y-value, and zero and the minimum y-value, 10(3)=30. Therefore, Ymax=30 and Ymin=-30.
