Ответ:
y = -2x - 3
so
case A) (-3, 33)
for x=-3
y=-2*(-3)-3> 6-3> y=3
3 is not 33
therefore
ordered pair is not a solution
case B) (8, -98)
for x=8
y=-2*(8)-3> -16-3> y=-19
-19 is not -98
therefore
ordered pair is not a solution
case C) (-9, 105)
for x=-9
y=-2*(-9)-3> 18-3> y=15
15 is not 105
therefore
ordered pair is not a solution
case D) (3, -39)
for x=3
y=-2*(3)-3> -6-3> y=-9
-9 is not 39
therefore
ordered pair is not a solution
the answer is
A,B,C and D
