Solution
Ste 1
From the table, we can see that y is a multiple of x.
Step 2:
When x = -1, y =
[tex]\begin{gathered} \text{Find the constant of proportionality k} \\ \text{k = }\frac{6}{-1}=\text{ }\frac{-12}{2}\text{ = }\frac{-24}{4}=\text{ }\frac{-36}{6}\text{ = -6} \end{gathered}[/tex]
Step 3
he equation relatiing y and x isy = kx
[tex]\text{y = -6x}[/tex]
Fnal answer
y = -6x
