Question

A house was purchased for $89,000. After 6 years the value of the house was $101,000. Find a linear equation that models the value of the house after x years.

Answer 1

Answer: y = 2000x + 89000

Explanation:

Given that;

initial purchase amount = $89,000

price after 6 years = $ 101,000

years = 6

now

slope = ( 101000 - 89000) / 6

slope = 12000 / 6

slope = 2000

therefore the linear equation that models the value of the house after x years will be;

y = 2000x + 89000
