What is the solution set of 4x = y and 2x2 − y = 0?

A.
{(0.5, -0.5), (2, -8)}

B.
{(0, 0), (2, 8)}

C.
{(1.5, 2), (8, 2)}

D.
{(-1.5, -2), (2, 8)}

{(0, 0), (2, 8)}

Step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
