document.write( "  y = (-1/2)x + b   |using ordered pair Pt(-5,-4) to solve for b
\n" );
document.write( " -4 = (-1/2)*5 + b
\n" );
document.write( " -8/2 + 5/2 = b
\n" );
document.write( "  -3/2 = b
\n" );
document.write( " y =   y = (-1/2)x -3/2  | The equation of the line in slope-intercept form
\n" );
document.write( "  y-intercept Pt(0,-3/2)
\n" );
document.write( " m = -1/2: as y increases/decreases by 1, x increases/decreases by 2 in opposite direction
