Answer:
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.
