Algebra.Com's Answer #52085 by checkley75(3666) ![]() 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 \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
