Answer:
The answer is t + 27
Step-by-step explanation:
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)
![k=\frac{9}{-3}=-3](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B9%7D%7B-3%7D%3D-3)
Now the relationship is:
y = -3x
For x=2
y = -3(2) = -6
