Through (2, -4); perpendicular to 6y=x-12 Equation of the line f(x) = ______ Find the product - (8x + 2)2 In 2006, the median price of existing home in some country was approximately $223,700. In 2001 the median price of an existing home was $151,800. Let y be the median price of an existing home in the year x, where x=0 represents 2001. Write a linear equation that models the median existing home price in terms of the year x. (line must pass through points (0,151800) and (5, 223700). y = ________ (type answer in slope-intercept form) Use this equation to predict the median existing home price for the year 2010. y = $___________________ Interpret the slope of the equation found in part a. Choose the coorect answser below. Every year, median price of home increases by $151,800 Every year, median price of home decreases by $151,800 Every year, median price of home increases by $14,380 Every year, median price of home decreases by $14,380 2006 population of a country was 50.7 million people. 2006 to 2050 country’s population is expected to descrease by 6.9%. Find expected population of the country in 2050. Round to nearest tenth of a million. Average annual number of cigarettes smoked by an adult continues to decline. 1997 to 2006, equation y=-49.7x + 1756.4 approximates this data. Here “x” is number of years after 1997 and “y” is average annual number of cigarettes smoked. If trend continues find year in which average number of cigarettes smoked is zero. Let y=0 and solve for x.
