To plot $-2.8$ on a number line:

Draw a straight line and mark integers.
Locate the integers $-3$ and $-2$ .
Divide the segment between $-3$ and $-2$ into 10 equal parts.
Each mark represents a tenth.
Count eight marks to the left from $-2$ (or two marks to the right from $-3$ ) to find $-2.8$ .
\begin{tikzpicture} \draw[<->] (-4.5,0) -- (0.5,0); \foreach \x in {-4,-3,-2,-1,0} \draw (\x,0.1) -- (\x,-0.1) node[below] {\x}; \foreach \x in {-2.9,-2.8,-2.7,-2.6,-2.5,-2.4,-2.3,-2.2,-2.1} \draw (\x,0.05) -- (\x,-0.05); \filldraw[red] (-2.8,0) circle (2pt) node[above right] {$-2.8$}; \end{tikzpicture}
The point marked in red represents $-2.8$ .
