A ladder leans against a building and reaches a height of 24 feet. If its base is 10 feet from the building, find the slope of the ladder.

Explain how to use the slope-intercept form to graph the equation \(y=-\frac{3}{5} x+2\)

In straight-line depreciation, explain why the slope of the line is called the rate of depreciation.

The price of computer equipment has been dropping steadily for the past ten years. If a desktop \(\mathrm{PC}\) cost \(\$ 6,700\) ten years ago, and the same computing power cost \(\$ 2,200\) three years ago, find the rate of decrease per year. (Assume a straight-line model).

Can the equation of a vertical line be written in slope-intercept form? Explain.
