Solve for all real numbers.
|2x+5|> 9

choices:
a.) (negative infinity, -4) or (4, infinity)
b.) (negative infinity, -7) or (2, infinity)
c.) (-7,2)
d.) (-4,4)

2x + 5 > 9             2x + 5 < - 9
2x > 9 - 5              2x < -9 - 5
2x > 4                   2x < - 14
x > 4/2                  x < -14/2
x > 2                     x < - 7

It would be answer B

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
