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.
The function y=mx+b represents a linear function, or a straight line. To graph the function y=5x+(-6) you must identify M and B. M represent slope which is found in front of the variable x. In this equation your slope (m) is 5.
