The length of the side of a square is equal to the perimeter of the square divided by four. Which shows the correct graph
relating the perimeter of a square on the x-axis to the side length of a square on the y-axis

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
