Coordinate Plane Relationships in Table

• the independent variable is distance
• the independent variable is d=25 t
• the dependent variable is time
• the dependent variable is distance

A carpenter charges $720 for 18 hours of work. She charges the same amount of money for each hour of work. Which table shows the relationship between the amount of time the carpenter works and the amount of money she charges?

• A

• B

• C

• D

Is the given table a proportional relationship? If so, write an equation that relates y to x.

• Yes;  y=1/3x

• Yes;  y=3x

• Yes;  y=5x 

• No

Write an equation for this relationship.

• y=1/5x

• y=1/2x

• y=2x

• y=5x

Is this graph proportional?

• Yes

• No

Write the equation for the table given. 

• y = 1/3x

• y = 3x

• y = 1/2x

Which graph is non-proportional?

• A

• B

• C

• D

Your friend says the following table DOES show a proportional relationship. Do you agree?

• False, because the y/x ratios do not have a direct variation and the graph doesn't goes through the origin

• True, because y/x does have a direct variation and goes through the origin

• True, because the x/y do not have a direct variation and doesn't goes through the origin

• False, because y/x does have a direct variation and goes through the origin

Does the table represent a proportional relationship? Use graph paper if necessary.

• Yes.

• No.

• Ordered Pair

• Pair

• Grouping

• Relationship
