The perimeter
First, calculate the distance between each point using:

So, we have:




So, the perimeter (P) is:


of" (and any subsequent words) was ignored because we limit queries to 32 words.
Ax+by=c
a=(-by+c)/x
b=(-ax+c)/x
c=ax+by
x=(-by+c)/a
y=(-ax+c)/b. or y= -a/b x + c/b which is slope intercept form
Answer:
x + y are either 2 or 4
Step-by-step explanation:
conclusion x + y = 2 OR 4
