Answer:

  The point (0, 25) is not a solution, but the point (-4, 10) is a solution.

Step-by-step explanation:

You can graph the inequality and check. The first point (0, 25) is on the boundary line, but that line is NOT part of the solution set. The second point (-4, 10) is well inside the solution space.

  (0, 25) is not a solution

  (-4, 10) is a solution

_____

You can put the values into the inequality and see if a true statement results.

  -10(0) +(25) > 25 . . . . False

  -10(-4) +(10) > 25 . . . . true

The first point is NOT a solution; the second point IS a solution.
