Xmin = -100 Xmax = 60 Ymin = -90 Ymax = 90

Work Step by Step

We need to choose an Xmin, Xmax, Ymin, and Ymax that will contain all the pairs: (-90, 0), (55, 80), (0, -80) Our Xmin must be lower than the lowest X value, -90. So we can choose -100 Our Xmax must be higher than the highest X value, 55. So we can choose 60 Our Ymin must be lower than the lowest Y value, -80. So we can choose -90 Our Ymax must be higher than the highest Y value, 80. So we can choose 90
