the table below shows the average yearly income, in dollars of individuals based on years of schooling
\n" ); document.write( "Years of schooling, x - average income, I
\n" ); document.write( "8 - $16000
\n" ); document.write( "10 - $19000
\n" ); document.write( "12 - $25000
\n" ); document.write( "14 - $28000
\n" ); document.write( "Model the data with a linear function using 10 years and 14 years and estimate the average yearly income for an individual with 16 years of schooling using this function. I would like to know, how do I set this problem up.
\n" ); document.write( ":
\n" ); document.write( "Look on the above pairs of numbers as x,y coordinates of a linear equation:
\n" ); document.write( "Although the coordinates don't look exactly linear.
\n" ); document.write( ":
\n" ); document.write( "Choose two pair, say the first and the last, and find the slope
\n" ); document.write( "x1 = 8, y1 = 16000; x2 = 14, y2 = 28000
\n" ); document.write( ":
\n" ); document.write( "Remember the slope equation: m = (y2-y1)/(x2-x1
\n" ); document.write( "The slope (m) of this problem:
\n" ); document.write( "m = \"%28%2828000+-+16000%29%29%2F%28%2814+-+8%29%29\" = \"%2812000%29%2F%286%29\" = +2000 is the slope
\n" ); document.write( ":
\n" ); document.write( "Use the point/slope formula to find the equation: y - y1 = m(x - x1)
\n" ); document.write( "y - 16000 = 2000(x - 8)
\n" ); document.write( ":
\n" ); document.write( "y - 16000 = 2000x - 16000
\n" ); document.write( "y = 2000x - 16000 + 16000
\n" ); document.write( "y = 2000x
\n" ); document.write( ":
\n" ); document.write( "It would look something like this:
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-4%2C+20%2C+-2000%2C+38000%2C+2000x%29+\"
\n" ); document.write( ":
\n" ); document.write( "To find out how much you make with 16 yrs of school, substitute 16 for x in the equation \n" ); document.write( "
\n" );
