Answer:
0.8
Explanation:
We have two points in the graph (60, 48) and (130, 104). Then, for every ordered pair (x, y) the constant of proportionality can be calculated as:
[tex]\frac{y}{x}[/tex]
So, If the points are (60, 48) and (130, 104), the constant of proportionality is:
[tex]\begin{gathered} \frac{48}{60}=0.8 \\ \frac{104}{130}=0.8 \end{gathered}[/tex]
Therefore, the answer is 0.8
