Since you know these equations represent straight lines you only need two points on each line to sketch the graphs. For the first equation when x = 0, y = 6 so (0, 6) is a point on the graph. Likewise when y = 0, x = 3 so (3, 0) is another point on the graph. Hence I can sketch the graph of y  2x = 6 For the second equation when x = 0, y = 5 so (0, 5) is a point on the graph. When y = 0 x is a fraction so I am going to choose a different point. When x = 1, y = 8 so (1, 8) is a point on the graph. Now when I plot both points on the same graph I can see the intersection point. Now try your equations. I have been sloppy and not put a scale on the axis. You need to make sure you include a scale.
