Please answer it correctly and please show work please help me I need it

4Y = 3X and 12Y = 9X. What equation describes proportional relationship? What is the constant of proportionality?

Answer 1

the equation is

y = 0.75x

And, the constant of proportionality is 0.75

Explanation:

The computation is shown below:

Given that

4y = 3x

And,

12y = 9x

Here the equation that represent proportional relationship is

4y = 3x

Divide both sides by 4

y = 3x ÷ 4

Now

12y = 9x

divides both sides by 12

y = 9 ÷ 12x

y = 3 ÷ 4x

y = 0.75x

so the equation is

y = 0.75x

And, the constant of proportionality is 0.75
