Wouldnt it be 21 idk dont pay attention to me lol
You multiply each point by 1/2 or 0.5 so if you have point A which is at (15,-3) it would become (7.5,-1.5) and you graph it there
The average would be the total yards divided by the number of carries:
Rewrite 15 3/4 as 63/4
Now divide by 7:
63/4 / 7 =
63/4 x 1/7 = 63/28 = 2 1/4
Because the total yards was a loss, which would be a negative number, the average is - 2 1/4 yards per play.
The length of the rectangle would be X2 - X1
The height of the rectangle would be Y2-Y1
Perimeter = 2 X length + 2 times height
The perimeter would be 2(X2-X1) + 2(Y2-Y1)
The first choice would be the correct answer.
