Based on the populations of the town from 2000 to 2008, the average rate of change of the population between 2002 and 2004 is -6.1%

The average rate of change between 2002 and 2006 is -4.88%

<h3>What is the average rate of change?</h3>

The average rate of change can be found as:

=Change in population / Population in base year

The average rate of change in population between 2002 and 2004 is:

= (77 - 82) / 82

= -6.1%

The average rate of change in population between 2002 and 2006 is:

= (78 - 82) / 82

= -4.88%

Equation for y and what if equals too
katen-ka-za [31]

The answer is y = 35x + 20.

In order to find this, start with two ordered pairs. For the purpose of this problem, we'll use (1, 55) and (2, 90). Now we use the slope formula to find the value next to x in the equation.

m(slope) = (y2 - y1)/(x2-x1)

In this equation (x1, y1) is the first ordered pair and (x2, y2) is the second. Plug in to the equation and solve.

m = (90 - 55)/(2 - 1)

m = 35/1

m = 35

Now that we have the slope, plug that into the equation along with either point to find the intercept (the last number).

y = mx + b

55 = 35(1) + b

55 = 35 + b

20 = b

Now that we have the slope and intercept, we can use each to fill in those blanks.

y = 35x + 20
