Algebra.Com's Answer #13610 by Died2Soon(6)![]() ![]() ![]() You can put this solution on YOUR website! First of all you need to get the Y by its self. You need to use the Formula Y=MX+B \n" ); document.write( "I'll use 2x-y=6 as the example. \n" ); document.write( "First subtract 2x from both sides like this: 2x-2x-y=6-2x \n" ); document.write( "You should get: -y=-2x+6 \n" ); document.write( "Now divide both sides by -1. You should get this: y=2x-6 \n" ); document.write( "The -6 is the Y-intercept and the 2 is the slope. So find -6 on the Y axis and put a point. Now go up 2 spaces and right 1 space, and place a point now draw the line. \n" ); document.write( "2x-y=4 is the same thing but with different numbers. \n" ); document.write( "just subtract 2x from both sides to get: -y=-2x+4 \n" ); document.write( "then divide by -1 on both sides to get: y=2x-4 \n" ); document.write( "The -4 is the Y-intercept and the 2 is the slope. So find -4 on the Y axis and put a point. Now go up 2 spaces and right 1 space, and place a point now draw the line. \n" ); document.write( "Good Luck \n" ); document.write( "=) \n" ); document.write( " |
