The original point and slope is (-3,6);m=1/2 I used the formula y-y1=m(x-x1)
\n" ); document.write( "--------------
\n" ); document.write( "Slope m = 1/2 thru the point (-3,6)
\n" ); document.write( "Use y = mx + b and the point
\n" ); document.write( "6 = (1/2)*(-3) + b
\n" ); document.write( "b = 15/2
\n" ); document.write( "--> y = x/2 + 15/2
\n" ); document.write( "2y = x + 15
\n" ); document.write( "x - 2y = -15
\n" ); document.write( "---------------
\n" ); document.write( "Using y-y1=m(x-x1)
\n" ); document.write( "y - 6 = (1/2)*(x+3)
\n" ); document.write( "2y - 12 = x + 3
\n" ); document.write( "x - 2y = -15
\n" ); document.write( " \n" ); document.write( "
\n" );
