What makes a graph proportional?

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

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

It is nonlinear and the line goes through the origin.

Why does this graph show a non-proportional relationship?

It does not go through the origin

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

What are the main characteristics of a proportional relationship between two variables when represented by a graph?

They are linear (straight line) and also pass through the origin.

The x to y ratio is a constant of proportionality.

Is the relation a function? Why.

No, because the x-value 11 has two y-values pair with it.

Yes, because the x-value 11 has two y-values pair with it.

Yes, because each x-value has only one y-value paired with it.

No, because each x-value has only one y-value paired with it.

Is this table a function and how can you tell?

No it's not a function because the x value 5 has y values of 10 & 12

Yes its a function because there are not variables for missing numbers

No it's not a function because the y value 4 repeated

No it isn't a function because the x value 2 is repeated with the same y-values

Which graph(s) show nonlinear functions?

Graph I, Graph II, and Graph III

Which answer choice is true?

The table represents a nonlinear function because the ratio of the change in the y value and the change in the x value is not constant.

The table represents a linear function because there is a pattern for the x-coordinates and y-coordinates.

The table represents a linear function because the ratio of the change in the y value and the change in the x value is constant.

The table does not represent a function because there is more than one output for at least one input.

Which relation is NOT a function?

{(1,-5), (-1,6), (1,5), (6,-3)}

{(1,-5), (3,1), (-5,4), (4,-2)}
