Answer:
The value of the constant of proportionality r is 1
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=r[/tex] or [tex]y=rx[/tex]
Find the value of the constant of proportionality r
[tex]r=y/x[/tex]
For x=5.8, y=5.8
substitute
[tex]r=5.8/5.8[/tex]
[tex]r=1[/tex]
The linear equation is
[tex]y=x[/tex]
therefore
The value of the constant of proportionality r is 1
