Answer:
(3, -8) and (2, -10)
Step-by-step explanation:
Given


Required
Select the true coordinate points in (3, -8) (2, 5) (-5, 1) (10, 3) (2, -10)
(3, -8)
x = 3 and y = -8



--- True



--- True
(2, 5)
x = 2 and y = 5



--- False (No need to check the other inequality)
(-5, 1)
x = -5 and y = 1


--- True


--- False
(10, 3)
x = 10 and y = 3


--- False (No need to check the other inequality)
(2, -10)
x = 2 and y = -10


--- True


--- True
Hence, the solution to the inequalities are:
(3, -8) and (2, -10)
