Raven’s parents bought a 20’ ski boat for $22,000. After 2 years, the boat was worth 17,500. Using x as the number of years and y as the boat value, graph the two points.

Part 1: [2 points] Describe the slope of the line which connects the two points.

Part 2: [3 points] How can your graph be used to predict the value of the boat in 5 years?

Part 3: [2 points] What is the projected boat value in 5 years?

please help me

luigi0210 · Answer

I would use the slope formula..

anonymous · Answer

idk how to do any of this tho

luigi0210 · Answer

$$\frac{22000-17500}{2-0}=\frac{4500}{2}=2250$$
That is the slope of the line: 
y=22000-2250x

luigi0210 · Answer

Part 1: The slope decreases with each year

luigi0210 · Answer

For part 2&3, just plug in 5 into the equation
