You can put this solution on YOUR website!
Y=mX+b IS THE POINT SLOPE FORMULA WHERE m=SLOPE & b=THE Y INTERCEPT.
\n" ); document.write( "GIVEN A POINT (3,-4) & A SLOPE (m) OF -5 THEN SUBSTITUTING 3 FOR X & -4 FOR Y WE GET:
\n" ); document.write( "-4=-5*3+b
\n" ); document.write( "-4=-15+b
\n" ); document.write( "b=-4+15
\n" ); document.write( "b=11 WHICH IS THE Y INTERCEPT. NOW THE FORMULA IS:
\n" ); document.write( "Y=-4X+11\r
