Question 356180
Let y=0.25x + 4 for the cost of going to a movie from 1985 to 1995. Let x represent the number of years since 1985.  What is the y-intercept in the linear model? What is the estimated cost of going the movies in 1991? What is the estimated cost of going to the movies in 1997?

..
y=0.25x+4   1985 ,x=0
y intecept = 4
..
1991, x=6
y=0.25*6 +4
y=1.5+4
y=5.5
...
applying the same linear model  1997 x=12
y=0.25*12+4
y=3+4
y=7
