In an inverse variation, y = -5 when x = -6. Write an inverse variation equation that showsthe relationship between x and y.Write the equation using a decimal or an integer.

Respuesta :

First we need to find the constant of variation

Let k be the conatant of variation

Since the variation is inverse, then;

y∝ 1/x

y=k/x

Substitute x=-6 and y=-5 in the above and solve for k

That is;

-5 = k/-6

cross multiply

k = 30

The equation is;

y = 30/x
