Answer:

Step-by-step explanation:

Draw the solid line y = 3x.  Now shade the region below this line.

I will simply invent a point:  (2, -1).  Here y = -1 and x = 2.  Either this point is in the shaded region or it is not.  Substituting 2 for x in y  ≤ 3x, we get

y ≤ 3(2), or y ≤ 6.  Is -1 less than 6?  YES.  So the (arbitrarily chosen) point (2, -1) is a solution of the given inequality.
