Math Problem Statement

Which among the following is a solution of x > 3y - 2?

Solution

The problem asks to determine which point among the given options satisfies the inequality x>3y2x > 3y - 2.

The options provided are:

  • (2, 3)
  • (5, 0)
  • (-2, 0)
  • (-2, 5)

We will check each point to see if it satisfies the inequality.

  1. For (2, 3): x=2,y=3x = 2, \quad y = 3 Check if: 2>3(3)22 > 3(3) - 2 2>922 > 9 - 2 2>7(False)2 > 7 \quad \text{(False)} So, (2, 3) is not a solution.

  2. For (5, 0): x=5,y=0x = 5, \quad y = 0 Check if: 5>3(0)25 > 3(0) - 2 5>025 > 0 - 2 5>2(True)5 > -2 \quad \text{(True)} So, (5, 0) is a solution.

  3. For (-2, 0): x=2,y=0x = -2, \quad y = 0 Check if: 2>3(0)2-2 > 3(0) - 2 2>02-2 > 0 - 2 2>2(False)-2 > -2 \quad \text{(False)} So, (-2, 0) is not a solution.

  4. For (-2, 5): x=2,y=5x = -2, \quad y = 5 Check if: 2>3(5)2-2 > 3(5) - 2 2>152-2 > 15 - 2 2>13(False)-2 > 13 \quad \text{(False)} So, (-2, 5) is not a solution.

Conclusion:

The correct solution is (5, 0).
