Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y varies as directly as the square of x, and y = 75/8 when x = 5, find y when x= 2

y=15/4

Step-by-step explanation:

start with general form y = kx. substitute in the pair of values you know for x and y.

75/8 = k(5) multiply both sides by 1/5 to solve for k, getting

15/8 = k

So your equation is y = (15/8)x substitute 2 for x to find your new y.

y = (15/8)2

y = 15/4
