Proportional Equations and Unit Rate Mastery

What does the variable 'k' represent in a proportional equation?

• The x-value

• The y-value

• The unit rate

• The slope

What is the first step in writing a proportional equation?

• Find the y-value

• Find the unit rate

• Find the slope

In the equation y = kx, what do x and y represent?

• Constants

• Unit rates

• Variables that change

• Slopes

If the unit rate is 2, what is the proportional equation?

• y = 2 + x

• y = 2x

• y = x/2

• y = x + 2

In a table, which set of numbers is always the x-values?

• The first set

• The second set

• The last set

• The third set

What is the unit rate if y = 280 and x = 10?

• 280

• 28

In a graph, where are the x-values located?

• Along the right side

• Along the left side

• Along the bottom

• Along the top

If the unit rate is 8, what is the proportional equation?

• y = 8 + x

• y = x + 8

• y = 8x
