(–3, 7) and (2, –13).
\n" ); document.write( "Y=mX+b
\n" ); document.write( "m= slope & b=the Y intercept.
\n" ); document.write( "m=(Y2-Y1)/(X2-X1)=(-13-7)/(2+3)-20/5=-4 ans. for the slope.
\n" ); document.write( "7=-4*-3+b
\n" ); document.write( "7=12+b
\n" ); document.write( "b=7-12
\n" ); document.write( "b=-5 ans. for the Y intercept.
\n" ); document.write( "Y=-4x-5 is the line equation thrugh these 2 points.
