Answer:

[tex]b=(3/4)a[/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 this problem the variables are a and b

so

[tex]b/a=k[/tex]

Find the value of k

For a=-4, b=-3

substitute

[tex]k=-3/-4=3/4[/tex]

The equation is equal to

[tex]b=(3/4)a[/tex]
