1, 0 , 8, and 2 would all lie on the y-axis
A = a^2.....where " a " is the size of 1 side
A = 256
256 = a^2...take sqrt of both sides, eliminating the ^2
sqrt 256 = a
16 = a
so each side is 16 ft....now we find the perimeter
P = 4a....where " a " is the size of each side
P = 4(16)
P = 64.......so they will need 64 ft of fencing <===
Answer:
We know that, two quantities are proportional when they vary directly with each other.
i.e. quantities x and y are proportional when they have the relation y = kx, where k is any constant called constant of proportionality.
Since, the quantities are in relation y = kx.
So, for x = 0 we get that the value of y = 0.
As, the point ( 0,0 ) satisfies this relation i.e. it is a solution of y = kx.
Hence, in proportional relationship, the graph will pass through ( 0,0 ).
