1. Find the equation of the line. Write the equation using function notation. Please show work.

Through (4,-5); perpendicular to 6y=x-12
The equation of the line is f(x) =____________________.

2. Please Show all work: In 2006, the median price of an existing home in some country was approximately $230,450. In 2001, the median price of an existing home was $157,700. Let y be the median price of an existing home in the year x, where x = 0 represents 2001.

a. Write a linear equation that models the median existing home price in terms of the year x. [Hint: The line must pass through the points (0,157700) and (5, 230450)].
Y=_____________________ (answer in slope-intercept form).

b. Use this equation to predict the median existing home price for the year 2010.
y=$___________________.
