Question

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

$\left(40,20\right),(-20,-80),(10,40)$

Short answer

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

$$\begin{gathered} X_{min}=-30, \\ {X}_{max}=60, \\ {Y}_{min}=-100, \\ {Y}_{max}=60, \\ {X}_{scl}=10 \\ {Y}_{scl}=10 \end{gathered}$$

Step-by-step solution

Step 1. Given information

The points are$\left(40,20\right),(-20,-80),(10,40)$

Step 2.Find the settings for viewig window

By observing given points,

The minimum value of$X$is$-20$

The maximum value of $X$is$40$

The minimum value of$Y$ is$-80$

The maximum value of $Y$is$40$

Write the setting for the viewing window

Take each unit on x-axis is $10$and

y-axis is$10.$
