To determine if an ordered pair is a solution to the system of inequalities, just put them into the system and check whether it can satisfy both.

For (-4, 2), (-2)*(-4) + 5 = 13, 13 ≥ 2, thus satisfy y ≤ -2x + 5
2*(-4) + 7 = -1, -1 ＜ 2, thus satisfy y > 2x + 7

For (-10, 7), (-2)*(-10) + 5 = 25, 25 ≥ 7, thus sa...
