To graph the inequality x - 2y ≥ -7, follow these steps:
-
Begin by graphing the boundary line, which is the equation x - 2y = -7. To do this, first rewrite the equation in slope-intercept form (y = mx + b): x - 2y = -7 -2y = -x - 7 y = (1/2)x + 7/2
-
Plot the y-intercept, which is (0, 7/2), and use the slope (1/2) to find another point. For example, move one unit to the right (increase x by 2) and two units up (increase y by 1), giving the point (2, 4).
-
Draw a dashed line through these two points. Because the inequality is ≥ (greater than or equal to), the boundary line should be drawn as a solid line.
-
Determine which side of the boundary line to shade by testing a point not on the line. A convenient point to test is the origin (0,0). Substitute the coordinates into the original inequality: x - 2y ≥ -7 0 - 2(0) ≥ -7 0 ≥ -7
Since 0 ≥ -7 is true, shade the side of the line containing the origin.
-
Finally, label the shaded region to indicate that it represents the solution to the inequality.
-
If needed, you can also label the boundary line for clarity.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
