see explanation.
Explanation:
Substitute the coordinates of the ordered pair into each inequality and check if they are true/false. If true then they are a solution.
#"using " x=2" and " y=-2#
#• y< x-3#
#rArr-2<2-3rArr-2<-1larr" TRUE"#
#• y> -x+1#
#rArr-2> -2+1rArr-2> -1larr" FALSE"#
#"Hence the ordered pair (2 ,-2)"#
#"is only a solution to " y< x-3#
