The following graph shows the relationship between the value of a building and the depreciation allowed for income tax purposes. 150000 100000 Value ($) 50000 (0.60000) (30,0) X 10 20 30 Time (years) A line is on the x y coordinate plane. The x-axis is labeled "Time (years)," and the y-axis is labeled "Value ($)." The line begins at the point (0, 60000), goes down and to the right, and ends at the point (30,0). 1A. Find the slope of the line between the two points shown on the graph. 18. Write a sentence that states the meaning of the slope in the context of this application. The value of the building is decreasing at a rate of Both must be complete to get thumbs up (a) and (b)
