Identify the constant of proportionality in the equation. 3y = 15x

5

Step-by-step explanation:

For direct variation y=kx, where k is the constant of proportionality

We need to get the equation in this form

3y = 15x

Divide each side by 3

3y/3 =15x/3

y = 5x

The constant is 5

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
