Find the slope and the y-intercept
\n" ); document.write( "5 - 1/4 y= 4x
\n" ); document.write( ".
\n" ); document.write( "The idea is to \"manipulate\" the given equation so that it is in the \"slope-intercept\" form of a line:
\n" ); document.write( "y = mx + b
\n" ); document.write( "where
\n" ); document.write( "m is the slope
\n" ); document.write( "b is the y-intercept at (0, b)
\n" ); document.write( ".
\n" ); document.write( "Starting with:
\n" ); document.write( "5 - 1/4 y= 4x
\n" ); document.write( "multiplying both sides by 4:
\n" ); document.write( "20 - y= 16x
\n" ); document.write( "subtracting 20 from both sides:
\n" ); document.write( "-y= 16x - 20
\n" ); document.write( "multiplying both sides by -1:
\n" ); document.write( "y = -16x + 20
\n" ); document.write( ".
\n" ); document.write( "Therefore,
\n" ); document.write( "m = -16 (slope is -16)
\n" ); document.write( "b = 20 (y-intercept is at (0,20))
\n" ); document.write( " \n" ); document.write( "
\n" );
