y < x + 1 is given, as are four possible answer choices.
One by one, subst. the answer pairs into this inequality and then determine whether or not the resulting inequality is true or not.
For the possible answer choice (-2,5), 5 < -2 + 1, or 5 < -1. FALSE.
Continue with the 2nd, 3rd and 4th points. Does the substitution of any of these pairs of coordinates result in a true inequality? Identify with one (or ones).
