Algebra.Com's Answer #364592 by MathHelper7(6)![]() ![]() You can put this solution on YOUR website! A bit complicated, but not too bad:\r \n" ); document.write( "\n" ); document.write( "You need to turn 3x+y=23 into y=-3x+23 ; Simple\r \n" ); document.write( "\n" ); document.write( " 3x+y=23 \n" ); document.write( " -3x -3x ; Minus 3x by both sides, it becomes a negative. \n" ); document.write( "--------------- \n" ); document.write( " y=-3x+23\r \n" ); document.write( "\n" ); document.write( "Now that you have both at the slope-intercept form (Mx+B, M being a number, B being a number, x being x) you can graph them!\r \n" ); document.write( "\n" ); document.write( "B is the y-intercept. So, whatever number in B is, that's where you put your first dot. -3x is your slope, but it isn't a fraction. When it isn't a fraction, you can assume it is: \n" ); document.write( "3 \n" ); document.write( "- \n" ); document.write( "1\r \n" ); document.write( "\n" ); document.write( "So, Rise over Run:\r \n" ); document.write( "\n" ); document.write( "3 (Rise) \n" ); document.write( "- \n" ); document.write( "1 (Run)\r \n" ); document.write( "\n" ); document.write( "So, move up 3 and over to the right 1, and put another dot, then up 3 over 1, another dot, again and again until you run out of room. If you're doing lines, just create the line going across the board using your points. Now for the other equation:\r \n" ); document.write( "\n" ); document.write( "y=x+3\r \n" ); document.write( "\n" ); document.write( "There is no slope! That's alright, anytime there is no slope, x becomes 1x, and using what I said above, 1x becomes\r \n" ); document.write( "\n" ); document.write( "1 \n" ); document.write( "- \n" ); document.write( "1\r \n" ); document.write( "\n" ); document.write( "So\r \n" ); document.write( "\n" ); document.write( "1 (Rise) \n" ); document.write( "- \n" ); document.write( "1 (Run)\r \n" ); document.write( "\n" ); document.write( "This time you go up 1, over 1, make another dot; up 1, over 1, make another dot and again and again until you run out of room then you make your line.\r \n" ); document.write( "\n" ); document.write( "Hope this helped!\r \n" ); document.write( "\n" ); document.write( "-MathHelper \n" ); document.write( " |
