Tricky Graphs Sometimes, graphs can be confusing. For instance, the xaxis of this graph counts by ones, but the yaxis counts by tens. Why would somebody want axes with different scales? They might want to graph a bunch of points with big ycoordinates, but small xcoordinates. The different scales make the graph easier to read. Here is a graph of the points (1, 20), (2, 30), and (3, 10): Changing scales makes the value of a point look bigger or smaller. Suppose that the value of the ycoordinate stood for your allowance. Then you might want to make the point look very small, so that you could persuade someone to raise your allowance. Here is the point (1, 2) graphed using two different scales: Which scale would you choose for your allowance? What about the distance from your home to school? Sometimes, people make graphs that skip several points. Don't let these graphs trick you! Here's a graph where the yaxis starts at 100: A fly is sitting at point (2, 102). Sam wants to eat the fly, so he crawls out to 2 on the xaxis and sticks his tongue straight up. Unfortunately, his tongue gets tangled in the warp zone before 100. (We told you about this kind of graph to make it harder for other people to trick you. Don't make graphs that skip points, or you could get tangled, too.) Sam will have to find another fly to eat. Luckily, he is good at finding things.
