Question

A scatter plot was made to show the number

of homes in a town based on the year. A
trend line was drawn on the graph with an
equation of y = 84x + 625 where x is the
number of years since 1995 and y is the total
number of homes in the fown.
Predict the number of homes in the
town in 2000

Answer 1

There will be 1045 homes in the town by the year of 2000.

Explanation:

From the question, it can be determined that

The equation given is y = 84x + 625.

The variables x and y are represented as :

• x is the number of years since 1995.
• y is the total number of homes in the town.

Now, we need to predict the number of homes in the town in the year 2000.

We know that, x is the number of years since 1995 to 2000.

∴ The value of x = No.of years from 1995 to 2000

⇒ x = 5 years

To calculate the y value :

Substitute x=5 in the given equation.

⇒ y = 84(5) + 625

⇒ y = 1045 homes.

∴ There will be 1045 homes in the town by the year of 2000.
