To answer this question we will graph the solution set of each inequality and then find the intersection of the solution sets.

1)


y\ge3x+3.

Since the inequality is not strict, then the border of the solution set is a solid line.

Notice that the solution set of the first inequality consists of all the points on the graph and above the graph of the line:


y=3x+3.

Therefore the solution set to the first inequality is:

2)


y<2.

The solution set of the above inequality consists of all the points such that its y-coordinate is less than 2, then its graph is:

Therefore the solution set to the given system of inequalities is:

Answer:

Two points on the solution set are (-2,-3) and (-1,0) and two points that are not on the solution set are (-2,2) and (-4,2).
