Question 1131780
Personally I like to create some sort of table, or quick jot notes of the useful information


In 1995: Total Area = 2.1 million acres
In 2011: Total Area = 8.5 million acres
Write a linear equation in slope y intercept form.

Remember: Slope y intercept form is (y)=(mx+b)
We can turn our data into the following points:
(1995, 2100000) and (2011, 8500000)
First we want to calculate the slope using: {{{(y[2]-y[1])/(x[2]-x[1])}}}
{{{(8500000-2100000)/(2011-1995)}}}
Therefore: The slope(m) = {{{(6400000)/(16)}}} = 400000
Now that we have the slope, we can take one of the points, I'll use (1995, 2,100,000) and plug it into our equation {{{y=mx+b}}}
{{{2100000=400000*1995+b}}}
{{{2100000)=798000000+b}}}
{{{2100000-798000000)=b}}}
{{{b=-795900000}}}
Now we can write our final equation:
{{{highlight(y=400000x-795900000)}}}
