Answer:
[tex]y=9.70[/tex]
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=k[/tex] or [tex]y=kx[/tex]
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
so
In this problem
[tex]y=3.3, x=1.65[/tex]
Find the value of k
[tex]y/x=k[/tex]
substitute the value of x and y
[tex]3.3/1.65=k[/tex]
[tex]k=2[/tex]
the equation is equal to
[tex]y=2x[/tex]
For [tex]x=4.85[/tex]
[tex]y=2(4.85)=9.70[/tex]
