for the inverse variation equation xy = k, what is the constant of variation, k, when x = -2 and y = 5?\n-10\n-\\frac{2}{5}\n\\frac{5}{2}\n10

Answer

Explanation:

Step1: Substitute values into equation

Given $xy = k$, substitute $x=-2$ and $y = 5$. So we have $(-2)\times5=k$.

Step2: Calculate the value of k

$(-2)\times5=-10$, so $k=-10$.

Answer:

A. -10
