Option 2: whenever it’s < or > it’s a dashed line but when it’s <= or >= it’s a solid line
Option 4: if you’ll insert (0,0) in the equation then you’ll get 0>-2 which is true so (0,0) is a solution. Another way to check is if (0,0) is in the shaded region of the graph
Option 5: in the equation-2 is the y-intercept which proves it intersects at (0,-2) on the y-axis
