Answer:

The point (1/2, 2) is a solution to y = 8x^2.

Step-by-step explanation:

Start with y = kx^2.  Substitute the y-coordinate (2) of the given point into this equation:  2 = kx^2.  Next, substitute the x-coordinate (1/2) into this equation:

2 = k(1/2)^2, or

2 = k/4, or k = 8.

The point (1/2, 2) is a solution to y = 8x^2.
