Understanding Proportional Group 1

Does the table represent a proportional relationship?

• Yes.

• No.

Identify the constant of proportionality (unit rate) from the points below:

(x , y) = (1,3) (2,6) (3,9) (4,12)

• 1

• 2

• 3

• 4

Write an equation for the proportional relationship shown from the points:

(x,y) = (1,5) (2,10) (3,15) (4,20)

Explain what the point (1, 4) on the graph of a proportional relationship means in terms of the situation.

• The unit rate is 4.

• The unit rate is 1.

• The relationship is not proportional.

• The point represents the origin.

• 
• 
• 
• 

Write an equation for this relationship.
