Road Grade From the top of a mountain road, a surveyor takes several horizontal measurements x and several vertical measurements y, as shown in the table ( x and y are measured in feet). (a) Sketch a scatter plot of the data. (b) Use a straightedge to sketch the line that you think best fits the data. (c) Find an equation for the line you sketched in part (b). (d) Interpret the meaning of the slope of the line in part (c) in the context of the problem. (e) The surveyor needs to put up a road sign that indicates the steepness of the road. For example, a surveyor would put up a sign that states 8grade on a road with a downhill grade that has a slope of 8100. What should the sign state for the road in this problem?

What price does your formula from part b project for January 2012 35 months after the Kindle was launched? Note: The web data were the basis for speculation that some day the Kindle would be free.
Depreciation A small business buys a computer for 4000. After 4 years the value of the computer is expected to be 200.For accounting purposes the business uses linear depreciation to access the value of the computer at a given time. This means that if V is the value of the computer at time t, then a linear equation is used to relate V and t. a Find a linear equation that relates V and t b Sketch a graph of this linear equation. c What do the slope and v-intercept of the graph represent? d Find the depreciated value of the computer 3 years from the date of purchase.
