We know that this ratio is directly because the two magnitudes go up.

In this case we will get the <u>proportionality constant</u> by dividing any term of the second magnitude by the first.

<h3>For example: </h3>

9 \:  \div  \:  3 \:  =  \:  \boxed{3}

Now that we know that k = 3, we can know how much "<u>y</u>" will be if <em>x = 5</em>.

We just multiply:

3 \:  \times  \: 5 \:  =  \: \boxed{ \bold{ 15}}

<h3>Answer: <u>y = 15</u></h3>
