2y=x+4 need the slope and intersection
\n" ); document.write( ".
\n" ); document.write( "To determine the \"slope\" and the \"y-intercept\", you can manipulate the given equation into the \"slope-intercept\" form of a straight 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( "To get it in the above form, simply divide both sides of the given equation by 2:
\n" ); document.write( "2y=x+4
\n" ); document.write( "y = (1/2)x + 2
\n" ); document.write( "This means:
\n" ); document.write( "m (slope) is 1/2
\n" ); document.write( "and
\n" ); document.write( "(0,2) is the y-intercept
\n" ); document.write( ".
\n" ); document.write( "To find the x-intercept, set y=0 and solve for 'x':
\n" ); document.write( "2y=x+4
\n" ); document.write( "2(0)=x+4
\n" ); document.write( "0=x+4
\n" ); document.write( "-4 = x
\n" ); document.write( "therefore,
\n" ); document.write( "(-4,0) is the x-intercept \n" ); document.write( "
\n" );
