Answer
$X_{max}=110,X_{min}=-20,Y_{max}=60,Y_{min}=-10,X_{scl}=10,Y_{scl}=10.$
Work Step by Step
If we select: $X_{min}$ to be lower than all x-coordinates of the points,
$X_{max}$ to be greater than all x-coordinates of the points,
$Y_{min}$ to be lower than all y-coordinates of the points,
$Y_{max}$ to be greater than all y-coordinates of the points,
$X_{scl}=10, Y_{scl}=10$ then we get a good solution. Thus $X_{max}=110,X_{min}=-20,Y_{max}=60,Y_{min}=-10,X_{scl}=10,Y_{scl}=10.$
