Answer:

  • III) (5, -1)

Step-by-step explanation:

Given relationship between the constants of the line ax + by +c = 0:

  • a - 5b - 3c = 8

We can try options, the obvious one is:

  • a = 0, b = - 1, c = - 1

In this case the line becomes:

  • 0x - y - 1 = 0
  • y = - 1

This gives us the point (5, - 1), the option III
