How do you graph #x – 2y = 6# by plotting points?
Choose two values for
First of all, you need to note that you have the equation of a line. In fact, a line is the only function you can plot knowing only two of its points (you simply need to connect them!)
So, we need two points which surely lie on the line.
To do so, we express the
So let's choose, for example,
Now, simply draw the points
