Creating Function Tables and Graphs

What is the first step in creating a graph from an equation?

• Choosing the y-intercept

• Drawing a line

• Creating a function table

• Plotting points on the graph

Why might it be difficult to graph the points (0, 0), (1/3, 1), and (2/3, 2)?

• They are not ordered pairs

• They are not on the graph

• They are difficult to estimate

• They are not part of the function
