The points (-1,x) and (4, 3x+1) are on a line with slope -17. What is x
\n" ); document.write( "slope=∆y/∆x=(3x+1)-x/(4-(-1))=(2x+1)/(4+1)=(2x+1)/5
\n" ); document.write( "(2x+1)/5=-17
\n" ); document.write( "2x+1=-85
\n" ); document.write( "2x=-86
\n" ); document.write( "x=-43
\n" ); document.write( "
\n" );
