document.write( "Using the standard slope-intercept form for an equation of a line y = mx + b
\n" );
document.write( "  where m is the slope and b the y-intercept. 
\n" );
document.write( " y=1/3x-4  |Slope m = (1/3) AND the slope of a line perpendicular to it is -3/1
\n" );
document.write( " Perpendicular Lines have slopes that are negative reciproclas of one another.

document.write( " y = -3x + b    |using Pt(0,1) to solve for b
\n" );
document.write( " 1 = -3*0 + b
\n" );
document.write( " 1 = b   EQ of this line is y = -3x+1
