(−2,−7)
(−1,−6)
(0,−5)
(1,−4)
(2,−3)

Explanation:

Because x is our independent variable, we choose the x integers and solve for y.

Usually, the five typical x integers are −2,−1,0,1, and 2.

If x=−2, we can plug that number in for x in our main equation. −2−5=−7, so if x=−2, y=−7.
(−2,−7).

We'd continue with this step for the next four numbers.

If x=−1,
−1−5=−6, so if x=−1, then y=−6.
(−1,−6).

If x=0,
0−5=−5, so if x=0, then y=−5.
(0,−5).

If x=1,
1−5=−4, so if x=1, then y=−4.
(1,−4).

If x=2,
2−5=−3, so if x=2, then y=−3.
(2,−3).
