Answer:
2.25
Step-by-step explanation:
to find slope it is (y2-y1)/(x2-x1)
(15.25-8.50)/(5-2)
6.75/3
2.25 is the slope

The length of a diagonal of a square is the side*sqrt(2). Let's call one side of the square: s
So we have 18 = s*sqrt(2)
18/sqrt(2) = s
18sqrt(2)/2 = s
9sqrt(2) = s
Since the perimeter is 4 sides we multiply by 4 to get 36sqrt(2) as the perimeter.
You scored 18 points in your fourth game because if you played 4 games and got 12 points each game that equals 48 points all together and if the average is 10 points for the first 3 games that equals 30 points for the three games so 48-30=18
