Answer:
5. the given ordered pair is not a solution 6. the given ordered pair is a solution 7. the given ordered pair is a solution
Step-by-step explanation:
5. 8 = -4(-2) => 8 = 8 (true)
8 = 1/2(-2) + 7 => 8 ≠ 6 (false)
the given ordered pair is not a solution
6. 3 + 5(1) = 8 => 8 = 8 (true)
4(3) - 5(1) = 7 => 7 = 7 (true)
the given ordered pair is a solution
7. -5 = 4 - 9 => -5 = -5 (true)
4 + (-5) = -1 => -1 = -1 (true)
the given ordered pair is a solution
