Answer:
The constant of proportionality is 6
Explanation:
Recall the equation for direct variation is
where
varies directly with
and
is the constant of proportionality. If we take any listed coordinate point, we can determine the value of
. I will use (20,120) as an example:
![y=kx\\\\120=k(20)\\\\6=k](https://img.qammunity.org/2023/formulas/mathematics/high-school/pwofxh36rcnr6pstkwa4ngkj6k7q9odf8r.png)
Therefore, the constant of proportionality is 6
