Question

Select a setting so that each given point will lie within the viewing window.

$\left(-80,-60\right),(20,-30),(-20,-40)$

Short answer

The setting so that each given point lie within the viewing window is

$$\begin{gathered} X_{min}=-100, \\ {X}_{max}=-40, \\ {Y}_{min}=-60, \\ {Y}_{max}=80, \\ {X}_{scl}=10 \\ {Y}_{scl}=10 \end{gathered}$$

Step-by-step solution

Step 1.Given information

The given points are$\left(-80,-60\right),(20,-30),(-20,-40)$

Step 2.Find the settings for viewig window

By observing given points,

The minimum value of is$-80$

The maximum value of is $20$

The minimum value of is$-40$

The maximum value of is $60$

Take each unit on x-axis is$10$

and y-axis is$10.$

Write the setting for the viewing window

localid="1646562136318" $$\begin{gathered} X_{min}=-100, \\ {X}_{max}=-40, \\ {Y}_{min}=-60, \\ {Y}_{max}=80, \\ {X}_{scl}=10 \\ {Y}_{scl}=10 \end{gathered}$$
