You have to find the rate, then multiply :)
Answer:
![y=24](https://tex.z-dn.net/?f=y%3D24)
Step-by-step explanation:
<u>Given:</u>
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
<u>Substitute:</u>
into ![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
![12=k\times2](https://tex.z-dn.net/?f=12%3Dk%5Ctimes2)
<u>Swap the sides:</u>
<u />![k\times2=12](https://tex.z-dn.net/?f=k%5Ctimes2%3D12)
<u>Divide both sides of the equation by the coefficient of variable:</u>
<u />![k=\frac{12}{2}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B12%7D%7B2%7D)
<u>Cross out the common factor:</u>
<u />![k=6](https://tex.z-dn.net/?f=k%3D6)
<u>Find the equation of the function:</u>
<u />![y=6x](https://tex.z-dn.net/?f=y%3D6x)
<u>Substitute:</u>
<u />![y=6\times4](https://tex.z-dn.net/?f=y%3D6%5Ctimes4)
<u>Calculate the product or quotient:</u>
<u />![y=24](https://tex.z-dn.net/?f=y%3D24)
