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.

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

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).
