The following table presents the average recommended weights for given heights for 25- to 29-year-old medium-framed women (wearing 1-inch heels and 3 pounds of clothing). Consider height to be the input variable and weight to be the output variable. As ordered pairs, height and weight take on the form (h, w). Designate the horizontal (input) axis as the h-axis and the vertical (output) axis as the w-axis. Since all values of the data are positive, the points will lie in quadrant I only. Plot the ordered pairs from the following height-weight table on a grid. 

h, HEIGHT (in.)	60	62	64	66	68	70	72	74
w, WEIGHT (lb)	110	124	131	138	145	152	159

2.  A recent study revealed that persons who text while driving are 23 times more likely to have an accident. Another study concluded that driving while texting is more dangerous than driving while under the influence of alcohol. It is estimated that persons in the age group of 18 to 24 send an average of 71 texts daily. The following table gives estimates of the average number of text messages (in billions) sent each month in the United States.

YEAR, y	2000	2001	2002	2003	2004	2005	2006	2007
Average number of monthly text messages (in billions), n	6	8	32	84	151	187	211

Identify the input and output variable quantities.
