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.
