How do you graph the inequality #2x + y > -2#?

Answer 1

Draw the straight line #2x + y = -2# that passes through #(-1, 0), ( 0, -2 )#. Shade the region above this line and enter therein #2x + y = -2#, The shaded region is the graph for the inequality.

#y = -2x-2# is the non-inclusive boundary line for the graph. For any point ( x, y ) above this line, #2x + y> -2#,

Answer 2

To graph the inequality 2x + y > -2, you first rewrite it in slope-intercept form, which is y = mx + b. To do this, subtract 2x from both sides to isolate y, giving y > -2x - 2.

Next, identify the y-intercept, which is -2 in this case. Plot a point on the y-axis at -2. Then, use the slope, which is -2 in this case, to find another point. Since the slope is -2, it means that for every 1 unit increase in x, y decreases by 2 units. So, from the y-intercept, move down 2 units and right 1 unit to plot another point.

Finally, draw a dashed line through the two points. Since the inequality is greater than (>) and not greater than or equal to (≥), the line should be dashed to indicate that the points on the line are not included in the solution set.

To determine which side of the line to shade, choose a test point not on the line, like (0, 0). Substitute the x and y values into the original inequality. If the statement is true, shade the region containing the test point. In this case, (0, 0) satisfies the inequality (0 > -2), so shade the region below the dashed line.

That's how you graph the inequality 2x + y > -2.

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.
