• True

• False

The total number of markers, m, contained in p packages can be represented by the equation m = 8p. Which of the following tables best represents this situation?

• 
•

What type of relationship is represented in this graph?

• Additive because it doesn't cross the origin

• Multiplicative because it crosses through the origin

What type of relationship is represented by this graph?

• Additive because it does not cross through the origin

• Multiplicative because it does cross through the origin

What type of relationship is represented in this equation:

x + 3 = y

• Additive and the graph would NOT cross through the origin

• Multiplicative and the graph would cross through the origin

What type of relationship is represented by this equation: 2(x) = y

• Multiplicative and the graph would cross through the origin

• Additive and the graph would NOT cross through the origin

What is the correct equation for an additive relationship?

• y = x+a

• x = y+a

• y = ax

• a/x = m
