An inclination of 45 translates to a slope of 1.
\n" ); document.write( "\"m=tan%2845%29=1\"
\n" ); document.write( "So using the point slope form of a line,
\n" ); document.write( "\"y-%28-9%2F2%29=1%28x-%28-5%2F2%29%29\"
\n" ); document.write( "\"y%2B9%2F2=x%2B5%2F2\"
\n" ); document.write( "\"x-y=9%2F2-5%2F2\"
\n" ); document.write( "\"x-y=2\"
\n" ); document.write( "So then when \"y=6\",
\n" ); document.write( "\"x-6=2\"
\n" ); document.write( "\"x=8\"
