## College Algebra (10th Edition)

If we select: $X_{min}$ to be lower than all x-coordinates of the points (e.g., $-20$); $X_{max}$ to be greater than all x-coordinates of the points (e.g., $110$); $Y_{min}$ to be lower than all y-coordinates of the points (e.g., $−10$); $Y_{max}$ to be greater than all y-coordinates of the points (e.g., $60$); and set $X_{scl}=10,Y_{scl}=10$; then we get a good solution.
