linear modeling

Question

the population of spring city was 15,000 in 1990, and 7250 in 2000. Create a linear equation to represent this situation. According to your equation, what will the population be in the year 2006?

Answer 1

The information given is really the coordinates for two points.

Use (1990, 15,000) and (2000, 7,250) to find the slope of the linear equation.

After finding the slope, you can write the equation using point-slope form.

To find the population in the year 2006, substitute 2006 for x and solve for y.
