You can put this solution on YOUR website!
You need to always solve for y; if no y, then solve for x. In this case, first subtract 2x from both sides to get $\"3y=-2x%2B12\"$ . Next, divide both sides by 3 to get $\"y=-%282%2F3%29x%2B4\"$ . Substitute a couple of values for x to solve for y in order to get two ordered pairs. Plot the two ordered pairs and connect with a straight line. The graph of this equation is: $\"graph%28300%2C300%2C-2%2C8%2C-5%2C5%2C-%282%2F3%29x%2B4%29\"$ \n" ); document.write( "
