In this, simply use the concept of understanding the graph and keep some points that there will be closed and open interval in the graph and also see the line where it starts and where it goes.

Here, the graph is given below:

In this, the line shows that the there will be a open interval at $-2$. The line goes right from the origin.

The equation of the inequality be like $y>-2$.

a. $y<-2$:In this, the equation tells that value of y is smaller than-2 but in the graph the lines goes from right of origin which means greater than -2. It is not correct option.

b. $y>-2$: In this, the equation tells that value of y is greater than-2so in the graph the lines goes from right of origin which means greater than -2. It is the correct option.

c. $y≤-2$: In this, the equation tells that value of y is smaller than or equal to-2but in the graph the lines goes from right of origin which means greater than -2 and also there is open interval at -2. So, It is not the correct option.

d. $yâ‰\yen -2$: In this, the equation tells that value of y is greater than or equal to-2, in the graph the lines goes from right of origin which means greater than -2 but there is open interval at -2. So, It is not the correct option.
