Hi there!

I believe your answer is:
Yes, it is a solution.

Here’s why:
⸻⸻⸻⸻
I am assuming that 'r' is supposed to be 'x'.
⸻⸻⸻⸻
[tex]y=11r-4\\------------\\\rightarrow -4 = 11(0) - 4\\\\\rightarrow -4 = 0 -4\\\\\rightarrow \boxed{-4=-4}[/tex]
⸻⸻⸻⸻
The ordered pair is a solution. You can also tell that it is a solution because the equation given is in slope-intercept form, and '-4' is in b's spot.
⸻⸻⸻⸻
[tex]y = mx+b[/tex]
⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
