The direct variation equation is
and the variation constant is
Explanation:
The equation for direct variation is y =kx where k represents the constant of variation.
When y = 1 and x = 15 the equation would translate to
1 = k(15)
To solve for k algebraically, divide by 15 on both sides of the equation.
This solves to
