One way is to plot points.

Choose three values for x; so they are easy to calculate, choose multiples of 3 (the denominator).

If x = 0, then y = (4/3)(0) + 2  =  0 + 2  =  2   --->   (0, 2)

If x = 3, then y = (4/3)(3) + 2  =  4 + 2  =  6   --->   (3, 6)

If x = 6, then y = (4/3)(6) + 2  =  8 + 2  =  10   --->   (6, 10)

You now have three points, plot them and draw the straight line that passes through those three points.

The reason that I choose three points and not just two is that if I make a mistake, then the points (most likely) will not be on a straight line, so I'll be able to check my work.
