Answer:
The average rate will be -11000 dollars per year.
Step-by-step explanation:
The price of a house in 2005 = $250,000
The price of a house in 2010 = $195,000
at x₁ = 2005, f(x₁) = 250,000
at x₂ = 2010, f(x₂) = 195,000
Using the formula to determine the average rate of change for the
house each year.
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [195,000 - 250,000
] / [2010-2005]
= -55000 / 5
= -11000
Therefore, the average rate will be -11000 dollars per year.

Answer:
- 7 / 4
Step-by-step explanation:
Slope = (y2 - y1) / (x2 - x1)
Slope = (1 - -6) / (-5 - -1)
Slope = - 7 / 4
