Math 7: Constant of Proportionality

The constant of proportionality can be found by finding the __________  _____________.

• unit rate
• ratio rate
• proportion answer
• rational number

How do you find the constant of proportionality from a table?

• $\frac{x}{y}$
  

• $\frac{y}{x}$
  

• x ⋅ y

• y ⋅ x

You can find the constant of proportionality (k) by doing:

• $k=\frac{y}{x}$

• $k=\frac{x}{y}$

• $k=x+y$

• $k=x-y$

A proportional relationship can be written as an equation in the form ____ = _____  _____

• y = k+x
• y = k-x
• y = kx
• y = k/x

The constant of proportionality in the equation 

 $y=\frac{1}{2}x$  is __________. 

• x

• y

•  $\frac{1}{2}$  
  

• 2
