Answer:


Step-by-step explanation:
equation (1): 
equation (2): y=2x
solve the system by substitution
step1: sub (2x) for y in equation 1:


step2: simplify the expression:


(divide by 2 for both sides)

To find the value for y sub 21/4 for x in equation 2:
y=2x
y=2×(21/4)

It's an example of rotation symmetry, if the image appears unchanged. If the rotation symmetry exists there is a one centre point around which an image appears unchanged.
