For an ordered pair to satisfy a function , it's a must that when you plug x , you get the value of y and vise versa :
y = -6x - 2
Check for pair ( -1,-8)
y = -6 * -1 -2 = 6 -2 = 4
y after substitution is not equal to given y ( 8 )
so refused ordered pair.
Check for pair (-3, 16)
y = -6 * -3 -2 = 18 -2 = 16
CORRECT , so this satisfy the function
and so on.
You would plug them in and see if they work. B and D work
