In 1985, $95 billion was spent on advertising in the United States, and in 2005, $270 billion was spent. Find and interpret the slope of the line passing through (1985, 95) and (2005, 270)

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
