Question

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 of a square on the y axis

Answer 1

The last image (The one going through points (4,1) and (8,2))

Explanation:

If the side length is y, and the perimeter is x, x is equal to that value times 4. This means the table of points would look like this:

x y

4 1

8 2

12 3

And so on. The only graph that is going through these points is the last one. The third graph is wrong because it's the opposite, (1,4) instead of (4,1), and the perimeter will be greater than the side length.
