You can put this solution on YOUR website!
m = -1 is the slope.
\n" ); document.write( "so,
\n" ); document.write( "y = -x + b
\n" ); document.write( ".
\n" ); document.write( "You can use the point given to find 'b'.
\n" ); document.write( ".
\n" ); document.write( "1 = -2 + b
\n" ); document.write( "b = 3
\n" ); document.write( ".
\n" ); document.write( "y = -x + 3
\n" ); document.write( ".
\n" ); document.write( "That is slope-intercept form.
\n" ); document.write( ".
\n" ); document.write( "Add x to both sides to get:
\n" ); document.write( ".
\n" ); document.write( "x + y = 3
\n" ); document.write( ".
\n" ); document.write( "That is \"standard\" form of a linear equation.
\n" ); document.write( ".
\n" ); document.write( "In general terms, the \"standard form\" is: Ax + By = C, where A, B, and C are constants.
\n" ); document.write( ".
\n" ); document.write( "Done.
\n" ); document.write( " \n" ); document.write( "
\n" );
