(-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).
