Answer:
<em>y=-6</em>
Step-by-step explanation:
<u>Proportions</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Substituting x=-3 y=9:
9 = k(-3)
Now the relationship is:
y = -3x
For x=2
y = -3(2) = -6
