Graph the equality y>=x-3
Solution
To start with, graph y = x -3 It is easiest if you just pick a small number for x, then solve for y. Here are a few: (3, 0), (4, 1), (5, 2), (0, -3). This should be enough. Graph these 4 points. The resulting line should be easy enough to see. The straight line will continue on forever in both directions. We symbolize this by drawing an arrow-head on each end. Now, to deal with the \"greater than\" sign. Lets find a point that fits the equation. To keep it simple, let\'s choose a small number for x, even one that we used before, like x = 3. Now find a number for y such that y > x - 3 So y > (3) - 3 = 0 , so y > 0 . Let\'s pick something simple, like y = 1 Since 1 > 0 , it works. So our point that fits the equation y > x - 3 will be (3, 1). Plot that point on your graph.

Solution
To start with, graph y = x -3 It is easiest if you just pick a small number for x, then solve for y.
Here are a few: (3, 0), (4, 1), (5, 2), (0, -3). This should be enough. Graph these 4 points. The
resulting line should be easy enough to see. The straight line will continue on forever in both
directions. We symbolize this by drawing an arrow-head on each end. Now, to deal with the
"greater than" sign. Lets find a point that fits the equation. To keep it simple, let's choose a
small number for x, even one that we used before, like x = 3. Now find a number for y such that
y > x - 3 So y > (3) - 3 = 0 , so y > 0 . Let's pick something simple, like y = 1 Since 1 > 0 , it
works. So our point that fits the equation y > x - 3 will be (3, 1). Plot that point on your graph.
