one of the lines is a horizontal line that crosses the y axis at (0,-1)...it has a solid line...it is shaded above the line...so the equation for that line is : y > = -1.
ur other line has a y int of (0,0), it has a slope of -1/2 ....it has a dashed line...it is shaded below the line.....so the equation for this line is : y < -1/2x
so ur answer is : y > = -1 and y < -1/2x
