1) x -3y = 3
\n" ); document.write( ":
\n" ); document.write( "rewrite equation 1 in slope - intercept form
\n" ); document.write( ":
\n" ); document.write( "y = x/3 - 1
\n" ); document.write( ":
\n" ); document.write( "the negative reciprocal of the slope, is the slope of a line perpendicular to the line in equation 1
\n" ); document.write( ":
\n" ); document.write( "slope of perpendicular line is -3
\n" ); document.write( ":
\n" ); document.write( "2) y = -3x +b
\n" ); document.write( ":
\n" ); document.write( "now use the point (-1,4) by substituting for x and y in equation 2
\n" ); document.write( ":
\n" ); document.write( "4 = -3(-1) +b
\n" ); document.write( ":
\n" ); document.write( "b = 1
