Answer:
[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
[tex]y \propto x[/tex]
[tex]y=kx[/tex]
As the [tex]x[/tex] increases or decreases, the output value [tex]y[/tex] will keep changing.
[tex]k[/tex] is called the constant of variation. The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another.
[tex]k=\frac{1}{5}[/tex]
