The first equation is
\n" ); document.write( " If a second line passes through the points (0,4) and has a slope of -1, find the solution to the system.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Equation of line with slope m and passing through(x1,y1) is\r
\n" ); document.write( "\n" ); document.write( " (0,4) ~(x1,y1) and has a slope of m=-1\r
\n" ); document.write( "\n" ); document.write( "y-y1= m(x-x1)\r
\n" ); document.write( "\n" ); document.write( "y-4= -1(x-0)\r
\n" ); document.write( "\n" ); document.write( "y-4=-x
\n" ); document.write( "y=-x+4\r
\n" ); document.write( "\n" ); document.write( "substitute y
\n" ); document.write( "y=2x-8. (given)
\n" ); document.write( "-x+4=2x-8\r
\n" ); document.write( "\n" ); document.write( "3x=12
\n" ); document.write( "x=4\r
\n" ); document.write( "\n" ); document.write( "Therefore y = -x+4= 0
\n" ); document.write( " the solution to the system of equations is (4,0)\r
