Determine Linear Function on Graph

Why does the graph represent a linear function?

• The graph has an equation that can be written in the form y = mx + b.

• The graph has an initial value other than 0.

• The graph increases or decrease at a constant rate.

• The graph crosses the x and y axis.

Does the graph represent a function?

• The graph is a function because it passes the vertical line test.

• The graph is a function because it passes the horizontal line test.

• The graph is not a function because it fails the vertical line test.

• The graph is not a function because it fails the horizontal line test.
