You can put this solution on YOUR website!
first step is to find slope:
\n" ); document.write( ":
\n" ); document.write( "4-(-7)/-7-4=11/-11=-1.......so m=-1........now any line parallel will have the same slope and any line perpendicular will hava the negative inverse of -1
\n" ); document.write( ":
\n" ); document.write( "which is 1
\n" ); document.write( ":
\n" ); document.write( "so using one of our points y-4=-1(x+7)(point slope form--->y-4=-x-7
\n" ); document.write( ":
\n" ); document.write( "y=-x-3.....y intercept(slope intercept) form .
\n" ); document.write( ":
\n" ); document.write( "line parallel could be y=-x+5....in standard from would be x+y=5
\n" ); document.write( ":
\n" ); document.write( "line perpendicular could be y=x+1...in standard form would be x-y=-1
\n" ); document.write( "
\n" );
