x1 y1 x2 y2
\n" ); document.write( "-7 -9 -4 -8
\n" ); document.write( "
\n" ); document.write( "slope m =(y2-y1)/(x2-x1)
\n" ); document.write( "(-8+9)/(-4+7)
\n" ); document.write( "(1/3)
\n" ); document.write( "m=0.33
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point (-7,-9) in
\n" ); document.write( "Y =mx+b
\n" ); document.write( "-9.00=-2.33+b
\n" ); document.write( "b= -9-2.33
\n" ); document.write( "b= -6.67
\n" ); document.write( "So the equation will be
