Question 1174385

A town's population has been growing linearly. In 2003 the population was 68,000. The population has been growing by 2200 people each year.

Write an equation for the population, P, x years after 2003.

Use the formula to find the population in 2009:
<pre>Rate of change/Slope: 2,200
y-intercept, with INITIAL year being 0, (0, 68,000)
Equation of a LINE: y = mx + b
Equation for the population, x years after INITIAL year/2003: {{{highlight_green(matrix(1,3, y, "=", "2,200"x + "68,000"))}}}
Substitute 6 (2009 - 2003) for x to find population in 2009.
