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 the solution of:

y < 3
4x + 2y > -4

dotted lines at y equals 3 and at four x plus two y equals negative 4, shading is to the right and below
 

Graph the solution of:

3x – 2y ≤ 6
x > -1

dotted line at x equals negative 1 and solid line at three x minus two y equals 6, shading is above and to the right
