I think the answer would be 21 zombies left. I used subtraction to figure this out.
The equation is y=2x+5 and there are two options like that so yea
They are perpendicular (the slope of the first line is 2/3, and the slope of the second line is -3/2, which are reciprocals of each other, meaning they are perpendicular)

Answer:
LK = 7
Step-by-step explanation:
We are using segment addition
NM + ML + LK = NK
x-6 + 9 + 2x-19 = 23
Combine like terms
x+2x -6+9-19 = 23
3x -16 = 23
Add 16 to each side
3x-16+16 = 23+16
3x = 39
Divide each side by 3
3x/3 = 39/3
x = 13
We want to find the value of LK
LK = 2x-19
=2(13) -19
= 26 -19
= 7
