    You need two points that line on the line, so that you can draw the line through them. Two of the easiest points to find are the x-intercept and the y-intercept.

    x-intercept: Let y = 0 and solve for x.
    y-intercept: Let x = 0 and solve for y.

    What you can do is first reform to y=....
    You probably know a straight line is determined by two points, so you can choose for example x=1 and x=2, enter this given x-values in the equation to get the y-values and draw the line.
