Question

A function describes a proportional relationship for a set of discrete data. What is true about the graph of that function?

It is a line connecting a series of points.
It is a line drawn only in the first quadrant.
It is a series of points that cannot be connected by a straight line.
It is a series of points that fall in a straight line but are unconnected.

Answer 1

It is a series of points that fall in a straight line but are unconnected.

Explanation:

Answer 2

The correct answer is the last choice.

When the data is discrete, it is separate. That means that the values are not connected.

And since it is proportional, it is also is a straight line.
