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.
Linear functions can always be written in the form f (x) =b + mx or f (x) =mx + b; theyâre equivalent where b is the initial or starting value of the function (when input, x = 0), and m is the constant rate of change of the function Many people like to write linear functions in the form.
