A house typically increases in value over time. What will be the nature of the graph?

Given a situation, “A house typically increases in values over the time.” that is to be graphed.

With time increasing, the value of a house also goes on increasing, depending upon current market conditions.

The value of the house can be decided every year. So, each year, its cost will go on increasing, so the relation between years and value of the house is an increasing function so that with the increases in the independent variable (years here), the value of a dependent variable (value of the house in thousand dollars) will also go on the increase at some constant rate almost.

As this relation will be an increasing relation, its graph should be best represented as a linear function having a positive slope, as shown above.
