Answer:

One invariant point;

Point A = (2, 0)

Step-by-step explanation:

The coordinates of the square vertices are;

O = (0, 0)

A = (2, 0)

B = (2, 2)

C = (0, 2)

Therefore, we have by 90° clockwise rotation;

O' = (2, 2)

A' = (2, 0)

B' = (4, 0)

C' = (2, 4)

Therefore, since only A' (2, 0) = A (2, 0), we have only one invariant point on the perimeter of the square when it is rotated 90° about the center (2, 0) which is the point A = (2, 0).

Answer:

if that line follows y=mx...then answer is A

But it seems not....when we divided valuse like 60/2=30

75/3=25....

ratio is not the same

Its hard to tell....You must know exact cordinations

I can tell you this

I can say this if y=60 and x=2 and....y=120 and x=4...then it is propotional...but it seems not..
