How to properly graphing linear equations
Learning how to graph linear equations is extremely easy. However, when doing so, it is literally vital for you to make sure that you do so in a neat and clean manner. Now, here’s what you need to do in order to graph a linear equation:
For an example, you need to graph the equation y = 2x + 3. Now, for this purpose, you initially have to draw a T-chart. Before you get confused, let me tell you that this is just a chart that basically resembles the letter T. In this chart, there would be a left column that is going to contain the values of x, whereas the one on the right is going to contain the corresponding values of y that you would need to compute. When considered together, the two of these values are going to formulate a point that will be (x, y). As an example, your chart is going to look something like:
Now, in order to graph linear equations, you need to pick the values of x. The one thing that is worthy of being mentioned here is that it is best for you to pick a minimum of three values as this is basically going to help you confirm that a straight line is being formed. Another thing that you need to do when graphing linear equations is that of spacing out the values of x a bit. What does that mean? Well, it means that it is best for you to pick out values of x like x = -2, 0, 2 etc. For instance:
However, the one thing that you need to bear in mind is that this isn’t really a rule – it is just something that will help you graph linear equations in a more neat and clean manner. Now, once you have picked the values of x, you need to compute their corresponding y values. Here’s what it’s going to look like:
Now, you need to plot the values over a graph, and it would look something like this:
Hope you’ve had fun learning how to graph a linear equation!
