The first condition is for the perimeter of the equation so:

Now the secon condition is that the sum of two sides should be:

so the negative option and 0 don't make sence dor a distance, then we try with the value of b=0.5
So in the first equation will be:

So the condition:

this is false, so the solution is
Hi so have you heard of KFC? It stands for keep flip change. You use it when adding or subtracting or when you're dividing fractions. So you keep the first part of the problem the same; you flip the sign of the second part, and change the sign of the third part. So -23.9- -9.3 becomes -23.9 + +9.3. So take away 9.3 from 23.9 and get 14.6. Whenever you add a positive to a negative like we do here, the answer will become a smaller negative number if the positive number is "smaller" than the negative number.
Answer:
value of y is 23/6
Step-by-step explanation:

(6,2y)
(4,-1)
m = (2y+1)/(6-4)
13/3 = (2y+1)/2
3(2y+1) = 2(13)
6y + 3 = 26
6y = 23
y = 23/6
