Let's see what to do buddy...

Step (1)
We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :

Our figure has 5 sides ;
So , sume the interior angles of it equals :

Step (2)
First look at the photo which I post.
According it we have :



Subtract the sides of the equation minus 465 :

And we're done.
Thanks for watching buddy good luck.

Answer: -2
I'm not so sure what it means by slope, but because I saw a pattern between x and y (it decreases by 2 every x value and decreases by 4 every TWO x values) values so I would pick -2. BUT I don't know if the answer is -4.
Step-by-step explanation:
Answer: Y= - 1/2x - 8
If you move y to one side by itself that’s what you’ll get and you can check this answer by multiplying each side by 2 and moving the x ti the left side and you’ll get your beginning equation
