Now, you try. Complete the Think & Click activity by looking at each problem below, thinking about it, and then clicking on the question to reveal the solution.

Graph y < 3x + 1.

Graph of y is less than three x plus one.
 

Graph y > -2x – 3.

Graph of y is greater than negative two x minus three
 

Graph x + y ≥ 3.

Graph of x plus y is greater than or equal to three
