The salmon population in a particular stream in Alaska decreased from 148,000 in 1997 to 129,000 in 2002
\n" ); document.write( " predict the salmon population in 2015.
\n" ); document.write( ":
\n" ); document.write( "Find the slope (m)
\n" ); document.write( "let x1 = 0, representing 1997
\n" ); document.write( "let x2 = 5, representing 2002
\n" ); document.write( "then
\n" ); document.write( "y1 = 148000; representing the salmon numbers
\n" ); document.write( "y2 = 129000
\n" ); document.write( ":
\n" ); document.write( "m = \"%28y2-y1%29%2F%28x2-x1%29\"
\n" ); document.write( ":
\n" ); document.write( "m = \"%28129000-148000%29%2F%285-0%29\" = \"%28-19000%29%2F5\" = -3800 is the slope
\n" ); document.write( ":
\n" ); document.write( "Find the equation using the point/slope form: y - y1 = m(x - x1)
\n" ); document.write( "y - 148000 = -3800(x - 0)
\n" ); document.write( "y = -3800x + 148000; is the equation
\n" ); document.write( ":
\n" ); document.write( "\"predict the salmon population in 2015\"
\n" ); document.write( "x = 18
\n" ); document.write( "y = -3800(18) + 148000
\n" ); document.write( "y = -68400 + 148000
\n" ); document.write( "y = 79,600 Salmon in 2015
