Answer:
umm... there is no problem
Your answer is A
It cannot be C because the line y > -2 uses the (>) greater than symbol.
When equations have a greater than symbol, they are graphed using a <u>dotted line. </u>
It cannot be D because the line is y ≤ - l x-1 l
with the less than or equal to sign (≤) , you use a <u>solid line</u> to graph
With the<u> greater than</u> symbol for y > -2 , the shaded region must be <em>above </em>this line.
With the <em>less than </em>or equal to sign in y ≤ - l x-1 l , the shaded region must be <em>below </em>the line.
