Math Problem Statement

Graph the following system of inequalities on the set of axes below: -2y < 3x + 12 x ≥ -3

Solution

The inequalities provided in the image are:

  1. 2y<3x+12-2y < 3x + 12
  2. x3x \geq -3

Let's break these down step by step:

First inequality: 2y<3x+12-2y < 3x + 12

  • To graph this, we need to first convert the inequality into slope-intercept form, which is y<mx+by < mx + b.
  • Divide both sides by 2-2 (note that when dividing by a negative number, the inequality sign reverses): y>32x6y > -\frac{3}{2}x - 6
  • The line corresponding to this inequality is y=32x6y = -\frac{3}{2}x - 6. Since the inequality is "greater than" (not equal), we will draw a dashed line to indicate that points on the line are not included in the solution.
  • The region above the line is the solution region for this inequality.

Second inequality: x3x \geq -3

  • This represents a vertical line at x=3x = -3, with shading to the right of the line (since x3x \geq -3).

Graphing Procedure:

  1. Graph the dashed line y=32x6y = -\frac{3}{2}x - 6.
  2. Shade the region above the dashed line.
  3. Draw a solid vertical line at x=3x = -3 and shade to the right of it.

Solution Set SS:

  • The solution set is the region where the shading from both inequalities overlaps. This is the area that satisfies both conditions.

Here are some related questions:

  1. How do you graph a system of linear inequalities?
  2. What does the inequality ymx+by \geq mx + b represent?
  3. How do you determine if a point lies within the solution region of an inequality system?
  4. What does a dashed line in an inequality graph indicate?
  5. How would you graph the inequality yx+3y \leq -x + 3?

Tip: When graphing inequalities, always start by sketching the boundary line and determine whether to use a dashed or solid line, then decide which side to shade!
