Getting error while inserting image

Question

I am trying to insert a image which is in .eps format from my computer into latex file. But I always get an error if I add the scale part but works fine without scale. Here is my code below.

Works fine:

    \begin{figure}
    \centering
    \includegraphics{Plot1}
    \caption{Sales vs Assets}
    \end{figure}  

Doesn't work fine:

\begin{figure}
        \centering
        \includegraphics[scale=.8]{Plot1}
        \caption{Sales vs Assets}
        \end{figure}  

Answer 1

You are using:

\usepackage{graphics}

But you need:

\usepackage{graphicx}

that extends package graphics and changes the syntax of \includegraphics to support key value options in the optional argument.
