A line through the points (9,2) and (7,x) has a slope of 7/3. Find x
\n" ); document.write( "**
\n" ); document.write( "slope=∆y/∆x=change in y/change in x
\n" ); document.write( "(2-x)/(9-7)=7/3
\n" ); document.write( "(2-x)/2=7/3
\n" ); document.write( "6-3x=14
\n" ); document.write( "3x=-8
\n" ); document.write( "x=-8/3
\n" ); document.write( "
\n" );
