Answer:

Lizzie came up with a divisibility test for a certain number $m \neq 1$:

Break a positive integer n into two-digit chunks, starting from the ones place. (For example, the number 354764 would break into the two-digit chunks 64, 47, 35.

Find the alternating sum of these two-digit numbers, by adding the first number, subtracting the second, adding the third, and so on. (In our example, this alternating sum would be 64-47+35=52.

Y > -x - 3
y = -x - 3
for x = 0 → y = -0 - 3 = -3 → (0, -3)for x = -3 → y = -(-3) - 3 = 3 - 3 = 0 → (-3, 0)
y ≤ 4x + 2
y = 4x + 2
for x = 0 → y = 4 · 0 + 2 = 2 → (0, 2)for x = -1 → y = 4 · (-1) + 2 = -4 + 2 = -2 → (-1, -2)
