x1 y1 x2 y2
\n" ); document.write( "-2 6 -9 1
\n" ); document.write( "
\n" ); document.write( "slope m =(y2-y1)/(x2-x1) 0.71
\n" ); document.write( "(1-6)/( -9-2)
\n" ); document.write( "(-5/-7)
\n" ); document.write( "m=0.71
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point (-2 ,6) in
\n" ); document.write( "Y =mx+b
\n" ); document.write( "6.00=-1.43+b
\n" ); document.write( "b=6-1.43
\n" ); document.write( "b=7.43
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y =0.71 x+7.43
\n" ); document.write( "y intercept = 7.43 \n" ); document.write( "
\n" );
