Math Problem Statement

graph the following system of a quality is graphically on the set of axes below state the coordinates of a point in the solution set. y<1/3x-2 and y less than or equal to -1/6x-5

Graph the following system of inequalities graphically on the set of axes below. State the coordinates of a point in the solution set. y < 1/3x - 2 and y ≤ -1/6x - 5

Solution

From the provided image, you are tasked with solving a system of inequalities graphically. Below is the solution process for the inequalities:

Inequalities:

  1. yx+2y \geq x + 2
  2. y2x7y \geq -2x - 7

Steps to Graph:

  1. Graph the first inequality (yx+2y \geq x + 2):

    • The boundary line is y=x+2y = x + 2. This line is solid because of the "greater than or equal to" (\geq) condition.
    • To plot:
      • Start with the y-intercept at (0,2)(0, 2).
      • Use the slope of 11 (rise over run) to plot other points: move up 1 and right 1 repeatedly.
    • Shade above the line, as yy is greater than or equal to the expression.
  2. Graph the second inequality (y2x7y \geq -2x - 7):

    • The boundary line is y=2x7y = -2x - 7. This line is also solid due to the "greater than or equal to" (\geq) condition.
    • To plot:
      • Start with the y-intercept at (0,7)(0, -7).
      • Use the slope of 2-2 (rise over run): move down 2 and right 1, or up 2 and left 1.
    • Shade above this line.

Solution Set:

The solution set is the region where the shaded areas of both inequalities overlap.

Finding a Point in the Solution:

  • Look for an easy-to-identify point within the overlapping region. For instance, a valid point may be (0,2)(0, 2), (1,4)(1, 4), or others depending on the region.

Would you like me to simulate the graph for better visualization or clarify further?

Tip:

Always test a point (like (0,0)(0, 0)) not on the boundary to verify which side of the line should be shaded.
