In 1980 the average price of a home in Brainerd County was $97,000. By 1986 the average price of a home was $109,000 Write a linear model for the price of a home, P, in Brainerd County as a function of the year, t. Let t=0 correspond to 1980

Answer 1

so treat your data as two ordered pairs
(0,97000) and (6,109000)
Just like in a normal x-y equation,
slope = (109000-97000)/(6-0)
= 12000/6 = 2000

using (0, 97000) , which would be the y-intercept
y = 2000x + 97000

Answer 2

what would be the x intercept

Answer 3

{0,9700} and {6,109000} just like in a normal x-y equation, slope={109000-97000}/{6-0} =12000/6=2000

using {0,97000} ,which would be the y-intercept y=2000x+97000
