Tabatha’s parents bought a new house in Florida for $110,000. After 10 years, the value was $145,000. Using x as the number of years and y as the house value, graph the two points.

Question

anonymous · Answer

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 house in 20 years? 

Part 3: [2 points] What is the projected house value in 20 years?

Are you comfortable with the equation for a straight line?

I just need help in part 2

frostbite · Answer

Well if you can do part 3 you can also do part 2 the same idea. The graph you show after the 10 years is the mathematical modeling of what we sepose is going to be the develupment of the value when we asume that the equation (equation for a straight line) that discribe the graph is true when we reach the 20 yeras.

We like to say our models become worse and worse as we get more and more away from out focus point (the data with make the graph with) like on this pic:
