y > -2x + 1?
plug in (0, 6)...... 6+%3E+-2%2A0+%2B+1.......6+%3E+1..a solution
plug in (0, 2) ........ 2+%3E+-2%2A0+%2B+1.......2+%3E+1..a solution

plug in (-1, 9) ........ 9+%3E+-2%2A%28-1%29+%2B+1.......9+%3E+3..a solution

plug in (1, -3) ........ -3+%3E+-2%2A1+%2B+1.......-3+%3E+-1..NOT a solution
