Write an equation to describe the relationship between x and y.

Sagot :

Answer:

Assume x is directly proportional to y :

[tex]y \: \alpha \: x \\ y = kx[/tex]

when y is 9, x is 2:

substitute to find value of k :

[tex]9 = (k \times 2) \\ k = \frac{9}{2} [/tex]

Therefore, equation is:

[tex]{ \boxed{ \boxed{2y = 9 x}}}[/tex]
