Algebra.Com's Answer #67518 by checkley75(3666) ![]() You can put this solution on YOUR website! 36) THE LINE FORMULA IS: \n" ); document.write( "Y=mX+b WHERE (m)=SLOPE & (b)=Y INTERCEPT. \n" ); document.write( "NOW SUBSTITUTE THE X & Y POINTS & SOLVE FOR THE Y INTERCEPT (b). \n" ); document.write( "0=-3/4*-2+b \n" ); document.write( "0=6/4+b \n" ); document.write( "b=-6/4 \n" ); document.write( "b=-1.5 FOR THE Y INTERCEPT. THUS THE LINE EQUATION IS: \n" ); document.write( "Y=-3X/4-1.5 OR Y=-.75X-1.5 ANSWER. \n" ); document.write( "----------------------------------------------------------------- \n" ); document.write( "38) 3X+5Y=15 \n" ); document.write( "5Y=-3X+15 \n" ); document.write( "Y=-3X/5+15/5 \n" ); document.write( "Y=-.6X+3 \n" ); document.write( "THUS A LINE PARALLEL TO THIS LINE & PASSING THROUGH (0,9) HAS A SLOPE OF -.6.
