Answer 1

9514 1404 393

Answer:

  (0, -8), (1, -11), (-1, -5)

Step-by-step explanation:

It is convenient to solve for y and choose values of x.

  y = -3x -8 . . . . . subtract 3x from both sides of the equation

Now, any integer value of x you choose will result in an integer value of y. Often, it is convenient to choose values near zero.

  x = -1, y = -3(-1) -8 = 3 -8 = -5 . . . . solution: (-1, -5)

  x = 0, y = -3(0) -8 = -8 . . . . solution: (0, -8)

  x = 1, y = -3(1) -8 = -11 . . . . solution: (1, -11)
