Given different coordinates below
[tex]\begin{gathered} (3,9.6) \\ (2,6.4) \\ (1,3.2) \\ (0.5,1.6) \end{gathered}[/tex]
The equation that connects the height to the width is given as
[tex]\begin{gathered} h=c\times w \\ h=\text{height} \\ c=\text{constant} \\ w=\text{width} \end{gathered}[/tex]
Pick a coordinate and substitute into the equation
[tex]\begin{gathered} (w,h)\rightarrow(3,9.6)\colon w=3,h=9.6 \\ h=c\times w \\ c=\frac{h}{w}=\frac{9.6}{3} \\ c=3.2 \end{gathered}[/tex]
