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.
2.4 Linear Functions The graph of a linear function is a line. To graph a linear function requires at least two points on the line. Often the easiest points to find are the x and y-intercepts. To find the y-intercept, replace x with 0 and solve for y; and to find the x intercept replace y with 0 and solve for x. Graph each linear function. Give the domain and range. 1. B:T;L 56 TF6 y-intercept (x = 0). x-intercept (y = 0).
