Slope for AB,
\n" ); document.write( "\"%28-4-%28-3%29%29%2F6-%28-2%29%29=-1%2F8\"
\n" ); document.write( "Line AB would have y-intercept \"b=y-mx=-4-%28-1%2F8%29%2A6=-4%2B3%2F4=-16%2F4%2B3%2F4=-13%2F4\";
\n" ); document.write( "Equation for line AB, \"highlight%28y=-%281%2F8%29x-13%2F4%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You want to know x when y=-8.
\n" ); document.write( "Solve the equation for x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-x%2F8=y%2B13%2F4\"
\n" ); document.write( "\"x=%28y%2B13%2F4%29%2F%28-8%29\"
\n" ); document.write( "\"x=-y%2F8-13%2F32\"
\n" ); document.write( "Substitute for y.
\n" ); document.write( "\"x=-%28-8%29%2F8-13%2F32\"
\n" ); document.write( "\"x=1-13%2F32\"
\n" ); document.write( "\"x=%2832-13%29%2F32\"
\n" ); document.write( "\"highlight%28x=19%2F32%29\", in this example, same as t.
