The x-intercept would have coordinates (10,0), while its y-intercept would be (0,-5). Hence the slope is \"%280--5%29%2F%2810-0%29+=+5%2F10+=+1%2F2\".
\n" ); document.write( "Then the slope of any line perpendicular to the given line would have slope -2. (Negative reciprocal of 1/2.)
\n" ); document.write( "
\n" );
