Step 1: Consider the provided complex expression,
-5i
The graph of the complex number is shown below,

Step 2: The absolute value of the expression is calculated below,
\(\displaystyle{\left|-{5}{i}\right|}=\sqrt{{{\left(-{5}\right)}^{{{2}}}}}\)
\(\displaystyle=\sqrt{{{25}}}\)
\(\displaystyle=\pm{5}\)
Therefore, the absolute value of the function is \(\displaystyle\pm{5}\).
