A typical graphing calculator has a height-to-width ratio of 23.
Is it square? Yes. Explanation: See solution.
A typical graphing calculator has a height-to-width ratio of 23. Therefore, the graphing calculator will display a square window if the height and width satisfy this ratio.
Height/Width=2/3
Let's find the height (y) and width (x) of the given viewing window.
Height:& 3-(-3)=6
Width:& 5-(-4)=9
Now we can use our formula.
