Answer:

(2, 5)

Explanation:

You want the ordered pair that is a solution to y ≤ 4x -3 from those on the list:

  • (1, 4)
  • (1, 5)
  • (-2, 5)
  • (2, 5)

Graph

The attachment shows a graph of the inequality, along with the offered solution points. The only solution among those shown is (2, 5). That solution lies on the boundary line. The "≤" symbol means the boundary line is included in the solution set.

Calculator

We can use a calculator to check the solutions, too. Rearranging, we have ...

4x -3 -y ≥ 0

The calculator in the second attachment is able to make this calculation using the list of x-values and the list of y-values. The solution list only has one number that is not less than zero. That corresponds to (x, y) = (2, 5).

Additional comment

We like to avoid having to enter the same equation over and over with different data. That is why we have chosen the solution methods here. A spreadsheet can repeat the calculation and comparison for you, too.
