Q. {y13x+3y>34x1 \left\{\begin{array}{l} y \geq-\frac{1}{3} x+3 \\ y>\frac{3}{4} x-1 \end{array}\right. \newlineWhich quadrants contain the solution to this system of inequalities?\newlineA. quadrants I, II, and IV\newlineB. quadrants I and II\newlineC. quadrants II and III\newlineD. quadrants I and IV
  1. Analyze Line Inequality: Analyze the first inequality y13x+3y \geq -\frac{1}{3}x+3. This inequality represents a line with a negative slope that crosses the y-axis at (0,3)(0, 3). Since yy is greater than or equal to this line, the solution set is above the line. This line divides the coordinate plane into two regions: above the line (where the inequality holds) and below the line (where the inequality does not hold).
  2. Analyze Positive Slope: Analyze the second inequality y > \frac{3}{4}x-1. This inequality represents a line with a positive slope that crosses the y-axis at (0,1)(0, -1). Since yy is greater than this line, the solution set is above the line. This line also divides the coordinate plane into two regions: above the line (where the inequality holds) and below the line (where the inequality does not hold).
  3. Determine Common Quadrants: Determine the quadrants where both inequalities are satisfied.\newlineThe first inequality's solution set is above the line with a negative slope, which includes parts of quadrants II, IIII, and IIIIII. The second inequality's solution set is above the line with a positive slope, which includes parts of quadrants II and IIII. The common regions where both inequalities are satisfied are in quadrants II and IIII.
  4. Confirm Excluded Quadrants: Confirm that no other quadrants are included in the solution set. Quadrant III is not included because the first inequality requires yy to be above the line with a negative slope, which does not occur in quadrant III. Quadrant IV is not included because the second inequality requires yy to be above the line with a positive slope, which does not occur in quadrant IV.
