This would give you a rectangular region bounded on two sides by these horizontal and vertical lines, and unbounded on the other two sides. A quarter plane, if you will.
To see why, consider these lines:
x = -1 is a vertical line that goes thru the x axis at -1, and x>-1 would be everything to the right of that line.
y = -3 is a horizontal line that goes thru the y axis at -3, and y <= -3 is everything below that line
So you would have a quarter plane bounded at the top by the line y = -3 (and including this boundary) and bounded on the left by -1 (and not including that boundary)
Draw it and you'll see

substitute to y = x, then graph this yet particularly of making use of a solid line, draw the line as a dashed line (which shows all values on the line do not fulfill the inequality y < x). Then, because of the certainty the graph is going in the time of the muse, %. any ordered pair and attempt the ordered pair indoors the inequality fact. for celebration, shall we %. the ordered pair (4, -2), which, if graphed, could be 4 contraptions to the surprising on the x-axis, and a couple of contraptions decrease than (on a vertical line from x = 4) on the y-axix. Now, ask your self: Is -2 < 4? because of the certainty the respond is beneficial, all aspects on the surprising part of the graph (it truly is a diagonal line in the time of the muse with a slope of a million to a million (m = a million/a million, or a million) increasing from left to perfect), yet not such because of the certainty the aspects on the line, fulfill the inequality fact. As a attempt, %. the ordered pair (-2, 4). Then ask: Is 4 < -2? of direction not, so all aspects to the left of the graph do not fulfill the fact. As a make beneficial for those aspects on the line, merely %. an element. Say, (5, 5). Then ask: Is 5 < 5. of direction not, so all aspects on the line do not fulfill the fact. Your very very final answer is the intersection of all aspects of the two inequality statements.

Think about it. This is text. You can't do a graph here.
