Proportional vs Nonproportional Relationships Graphs

The table shows the distance of a train from a station and the time it will take to arrive. The relationship is linear. Is it proportional or nonproportional?

• Proportional

• Nonproportional

• Neither

• Both

Determine if the linear relationship is proportional or nonproportional. 

• Proportional

• Nonproportional

• Neither

Write an equation for this situation.

• y=9.75x

• y=19x

• y=19.25x

• y=9.5x

Why does this graph show a non-proportional relationship?

• It doesn't, it is proportional because it is a straight line

• It goes through the origin

• It does not go through the origin

• It is a straight line

Is the graph proportional or non proportional? Assume it is going through point (0,0).

• Proportional

• Non-Proportional

Which graph is non-proportional?

• A

• B

• C

• D

Is the graph proportional or non proportional?

• Proportional because it is a straight line and passes through the origin (0,0).

• Non-Proportional because it doesn't pass through the origin (0,0).

Which graph is proportional?

• A

• B

• C and D

• All of the graphs are proportional

Is the given table a proportional relationship? If so, what is the constant of proportionality?

• Yes; 1/3

• Yes; 3

• Yes; 5

• No

What makes a graph proportional?

• It is linear and goes through the point (0,4).

• It is linear and goes through the point (0,0). The ratio between y and x values is constant.

• It is a curvy line.

• It is nonlinear and the line goes through the origin.
