Answer:
[tex]y=3/x[/tex] or [tex]yx=3[/tex]
The graph in the attached figure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]
so
in this problem we have
y=0.75 when x=4
Find the value of k
[tex]y*x=k[/tex]
[tex]k=0.75*4=3[/tex]
The equation is equal to
[tex]y=3/x[/tex]
using a graphing tool
see the attached figure
