hi there,
\n" ); document.write( "Gradient = y(2) - y(1)/x(2) - x(1)
\n" ); document.write( "-5 = 0 - (-1)/ x - 2
\n" ); document.write( "-5 = 1/x-2
\n" ); document.write( "Cross multiply
\n" ); document.write( "-5(x - 2) = 1
\n" ); document.write( "-5x + 10 = 1
\n" ); document.write( "-5x = 1 - 10
\n" ); document.write( "-5x = -9
\n" ); document.write( "x = 9/5
\n" ); document.write( "Hope this helps:-)
\n" ); document.write( "
