What is the linear inequality of y> -2

Your question is a bit ambiguous.  Are you supposed to describe the inequality in words?  or to graph it?  Please share the instructions and don't use "What is ... "

y>-2 can be graphed easily.  Think:  the x-axis is the line y=0.  The line y= -2 is also a horiz. line, but it passes thru (0, -2) instead of thru the origin (0,0).

Because of the inequality symbol, you must draw y = -3 as a dashed (not solid) line.

Last, you'd need to shade the entire area above the dashed line y = -3.  The shaded area is the "solution" of y>-2.

Take midpoint of two co ordinate of diameter of circle.
