How do you graph #y=6x-3# by plotting points?
First of all, note that this function is a polynomial, because it can be written as a sum of powers of a variable with some coefficients:
In your case,
And it is because
To draw a line, you only need two points, so that you can connect them. To sample two points from the equation, you need to choose two points
Of course, it makes no sense to choose "difficult" points to compute, since any couple will work. For this reason, you may choose, for example,
Now you only need to draw
