Answer: (-2, -5) is not a solution.

Step-by-step explanation:

To check if (-2, -5) is a solution of x - 4y = 8 or not, we will substitute it into the given equation. If the result is a true statement, it's a solution.

Given equation:

x - 4y = 8

Substitute -2 for x and -5 for y:

(-2) - 4(-5) = 8

Multiply -4 by -5:

(-2) + 20 = 8

Subtract 2 from 20:

18 ≠ 8

We can also graph the equation, see attached. You will see that the point (-2, -5) does not lie on the line x - 4y = 8.
