Find the inequality represented by the graph

You can see the gradient of the line is -1.5 with y-intercept -2.

So, the line can be represented with the equation y = -1.5x - 2.

The shaded region is below the line (including the line). So, the possible y values are those less than or equal to the y values represented by the line.

This gives y ≤ -1.5x - 2

Hope i can you!
