Answer:
1/3
Step-by-step explanation:
1. When we divide any x-input by the y-input, we get 3. This is the same as multiplying the x-input by 1/3 to get the y-input. Let's see if it works!
- [tex]3 * \frac{1}{3} = \frac{3}{3} = 1[/tex]
- [tex]6 * \frac{1}{3} = \frac{6}{3} = 2[/tex]
- [tex]12 * \frac{1}{3}= \frac{12}{3}=4[/tex]
- [tex]15*\frac{1}{3}=\frac{15}{3} =5[/tex]
2. Great! All our x-inputs and y-inputs match up, meaning the constant of proportionality, k, is 1/3.
