It's the number times 4 so 0 times 4 is 0. 3 times 4 is 12. 9 x 4 is 36.

Answer:

c = 4

Step-by-step explanation:

The given points are

[tex](0,0);(3,12);(9,36)[/tex]

Notice that each coordinate was increased by a factor of 3,

[tex]3 \times 3=9\\12 \times 3= 36[/tex]

Then, we divide the vertical variation by the horizontal variation

[tex]c=\frac{36-12}{9-3}=\frac{24}{6}\\ c=4[/tex]

Therefore, the constant of variation is 4.
