Algebra.Com's Answer #27679 by jmg(22)![]() ![]() ![]() You can put this solution on YOUR website! There are two different ways to graph this. \n" ); document.write( "The easiest if you have been working with slope and intercepts is to graph the y-intercept which is the 2. (that means to go up 2 on the graph and put a dot). \n" ); document.write( "Then use the slope, which is 3. \n" ); document.write( "If you write that as a fraction 3/1 you can use rise/run. \n" ); document.write( "This means that you start at the 2 you just graphed and rise or go up 3, and then go to the right or run 1. \r \n" ); document.write( "\n" ); document.write( "So you should have a point graphed at (0,2) and (1, 5). Now just connect the dots.\r \n" ); document.write( "\n" ); document.write( "IF YOU HAVE NOT WORKED WITH SLOPE AND Y-INTERCEPT: \n" ); document.write( "Then make a table of solutions. Another words pick some numbers for x, plug them in and see what you get for y. Then graph the points\r \n" ); document.write( "\n" ); document.write( "Let x=0, then y = 3*0 + 2, so y=2. Graph the ordered pair (0, 2)\r \n" ); document.write( "\n" ); document.write( "Let x = 1, then y = 3*1 + 2 , so y = 5. Graph the ordered pair (1, 5)\r \n" ); document.write( "\n" ); document.write( "Let x = 2, then y = 3*2 + 2, so y = 8. graph the ordered pair (2, 8)\r \n" ); document.write( "\n" ); document.write( "Now try some negatives to get a good representation of the whole graph.\r \n" ); document.write( "\n" ); document.write( "Let x = -1, then y = 3*-1 + 2, so y = -1. Graph (-1, -1)\r \n" ); document.write( "\n" ); document.write( "Let x = -2, then y = 3*-2 + 2, so y = -4.
