The ordered pair (5,6) is a solution of a direct variation equation. what’s the equation?

direct variation equations are of the form

  y = kx

for some constant k

if (5,6) is a solution to this equation, then this means that when x = 5, y = 6. substituting will allow us to solve for k, the constant.

  6 = k·5

dividing both sides by 5, we get

  k = 6/5

so the direct variation equation is

  y = (6/5)x

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
