Algebra.Com's Answer #28664 by checkley71(8403)![]() ![]() ![]() You can put this solution on YOUR website! USE THE Y=mX+b METHOD TO FIND THE SLOPE AND THE X & Y INTERCEPTS PLOT THE TWO LINES AND DEFINE THE INTERSECTION.\r \n" ); document.write( "\n" ); document.write( "THUS 3X-6Y=9 OR -6Y=-3X+9 OR Y=X/2-3/2 THAT GIVES YOU A SLOPE OF 1/2 & A Y INTERCEPT OF -3/2. THE X VALUE IS OBTAINED BY SETTING Y=0 0=X/2-3/2 OR X/2=3/2 OR X=3 SO THESE TWO OINTS ARE (0,-3/2) & (3,0)\r \n" ); document.write( "\n" ); document.write( "THE SECOND EQUATION IS SOLVED THE SAME WAY X-2Y=3 OR -2Y=-X+3 OR Y=X/2-3/2 \n" ); document.write( "WHAT THIS TELLS YOU IS THAT THESE TWO EQUATIONS ARE FOR THE SAME LINE HAVING THE SAME SLOPE, THE SAME Y INTERCEPT AND THE SAME TWO POINTS. \n" ); document.write( " |
