Answer: (-4, -6)

Explanation:

Solving by graphing

[] See attached

() The only point in the required range is point (-4, -6)

Solving by plugging-in

I will figure out what the correct option is by plug them into the first equation. Since only one of these options is true, I do not need to do the second equation.

[✗] Let's check point (4, 10)

() 10 < (1/4)4 - 4

10 < 1 - 4

10 < -3 is false, so this answer is incorrect

[✗] Let's check point (-4, 5)

() 5 < (1/4)-4 - 4

5 < -1 -4

5 < -5 is false, so this answer is incorrect

[✗] Let's check point (-4, -4)

() -4 < (1/4)-4 - 4

-4 < -1 -4

-4 < -5 is false, so this answer is incorrect

[✓] Let's check point (-4, -6)

() -6 < (1/4)-4 - 4

-6 < -1 - 4

-6 < -5 is true, so this answer is correct
