2. a style of dance music marked by some of the features of jazz.
The graph of y = 2x+1 is a straight line. 1  When x increases, y increases twice as fast, hence 2x. 2  When x is 0, y is already 1.  So: y = 2x + 1.
This means that this equation describes a function. Example 3 Determine If An Equation Represents a Function Does the equation xy22 4 describe y as a function of x? Solution This example specifies y as a function of x so we know that the independent variable is x and the dependent variable is y. Like the
