You can put this solution on YOUR website!
This is a line. You should always turn it into the equation of a line form, y=mx+b.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x-2y = 6
\n" ); document.write( "x-6 = 2y
\n" ); document.write( "x/2 -6/2 = y\r
\n" ); document.write( "\n" ); document.write( "y = x/2 - 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Comparing this to y=mx+b, we see that m=1/2 and b= - 3.\r
\n" ); document.write( "\n" ); document.write( "This means the slope is 1/2 (it goes up 1, right 2, up 1, right 2, and so on...) and the line crosses the y-axis at y=-3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can graph it by putting a dot at y=-3 to start. This point is (0,-3)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then travel up 1, over 2. This will take you to the point (2,-2).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can continue this 'staircase', and your next 3 points will be:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(4,-1)
\n" ); document.write( "(6,0)
\n" ); document.write( "(8,1) \n" ); document.write( "
