Compare two functions represented in different ways: equations, graphs, tables, or verbal descriptions.

Compare a linear equation to a table

Problem

Compare the line \(y=2x-1\) with the displayed table.

Answer choices

The table represents the same function because when x = 0 both the table and the equation have y = -1.

The table does not represent the same function because its y-values increase by 3 each time x increases by 1, while the equation has slope 2.

The table represents the same function because the y-values increase by 2 each time x increases by 1, so the matching slope is enough.

The table does not represent the same function because it has the same slope as y = 2x - 1, but its y-intercept is 3 instead of -1.
