Points: 1 pt

We can write the equation as
\[
(5) + (-7)
\]

\begin{tikzpicture}[scale=0.9, every node/.style={inner sep=0pt}]
  % green dots
  \foreach \y in {4,3,2,1,0} {
    \fill[green!60!black] (0,\y) circle (0.12);
  }
  % red dots
  \foreach \y in {6,5,4,3,2,1,0} {
    \fill[red!75!black] (4,\y) circle (0.12);
  }
  % cancellation lines
  \foreach \y/\ry in {4/4,3/3,2/2,1/1,0/0} {
    \draw[thick] (0.18,\y) -- (3.82,\ry);
  }
\end{tikzpicture}

2 red dots remaining

Final answer:
