The graph below contains a linear model that approximates the relationship between the size of a home and how much it costs. The [i]x[/i]-axis represents size in square feet, and the [i]y[/i]-axis represents cost in dollars. Describe what the slope and the [i]y[/i]-intercept of the linear model mean in terms of housing prices.
[list=1] [*]Find the equation of the linear fit. [*]Determine the units of the slope. [*]Describe what the slope means in context. [*]Determine the units of the [i]y[/i]-intercept. [*]Describe what the [i]y-[/i]intercept means in context. [/list]
