Graphs
In science class, we collect data and show the relationship of the data by using a graph. Graphs range from linear to rational to all the others. So far, in my class, we have only gone over the linear graphs and the rational graphs. Within linear graphs, there are graphs that show a relationship that is directly proportionate, directly linear and no relation. In a linear graph that is directly proportionate, the line is straight and crosses the y-axis at zero. This indicates that the rate of change is constant and that when the x value is zero, the y value is also zero. On the other hand, in a directly linear relationship, the line is straight but does not cross the y-axis at zero. This shows that the rate of change of the data is constant and that when x is zero, y is something other than zero. For example, when I did the Hex Nut lab in physics, the y was not zero, it was 16.4. This y intercept represents the total mass of the con...
