Write an inverse variation equation that relates x and y if y=-7 when x=-3 find y when x=-3

y = 21/x

y = - 7

Step-by-step explanation:

y = k/x

-7 = k/-3

k = - 7*-3 = 21

y = 21/x

y = 21/-3

y = - 7

-7

Step-by-step explanation:

Inverse variation is characterized by the equation: y = k/x, where k is a constant.

Here, we're given values of y and x, so let's use them to find k:

y = k/x

-7 = k / (-3)

k = (-7) * (-3) = 21

Our equation is now: y = 21/x

Finally, plug in - 3 for x:

y = 21 / (-3) = - 7

The answer is - 7.
