To determine which ordered pair is a part of the solution set for the equation \( y = 2.5x - 2 \), we can substitute the \( x \) values from the ordered pairs into the equation and see if the resulting \( y \) value matches.

  1. For the point (-2, 0): \[ y = 2.5(-2) - 2 = -5 - 2 = -7 \] This point does not satisfy the equation since \( 0 \neq -7 \).

  2. For the point (2, 5): \[ y = 2.5(2) - 2 = 5 - 2 = 3 \] This point does not satisfy the equation since \( 5 \neq 3 \).

  3. For the point (2, 3): \[ y = 2.5(2) - 2 = 5 - 2 = 3 \] This point satisfies the equation since \( 3 = 3 \).

Since (2, 3) satisfies the equation, the correct answer is:

(2, 3)
