In 1980, the average price of a home in Lake County was $92,000. By 1986, the average price of a home was $104,000. Which of the following is a linear model for the price P of a home in Lake County, in terms of year t? Let t = 0 correspond to 1980.
A) P = 2,000t + 92,000 (B) P = 104,000 - 2,000t
C) P = 104,000 - 12,000t (D) P = 12,000t + 92,000
Answer by scott8148(6628)   (Show Source):
You can put this solution on YOUR website! over six years (1980 to 1986) the price increases 12000 (104000-92000)
___ so the slope of the price line is 2000/yr
when t=0, P=92000 ___ this is the intercept
in slope-intercept form ___ P = 2000t + 92000
