Answer:
[tex]y=-0.60x[/tex]
The graph in the attached figure
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
step 1
Find the constant of proportionality k
we have the point (5,-3)
[tex]k=y/x[/tex]
substitute
[tex]k=-3/5=-0.6[/tex]
The equation is
[tex]y=-0.60x[/tex]
using a graphing tool
