What does the point (2,4) mean in the context of the problem?

Will the point (14, 105) be on this graph?

• Yes

• No

Is this graph proportional?

• Yes

• No

This graph is NOT proportional because . . .

• It has the same CoP

• It is not a continuous straight line

• It does not start at the origin (0,0)

Which is the correct equation for this relationship?

• y = 1/5x

• x = 5y

• y = 5x

In the equation y = k x

What does k represent?

• input

• Independent Variable

• Dependent Variable

• Constant of Proportionality
