Given that y varies inversely with x, and x = 7 and y = 4, find the value of k.

Back

k = 28.

What is the significance of the constant k in inverse variation?

Back

k represents the product of x and y, remaining constant.

What is the relationship between direct variation and inverse variation?

Back

In direct variation, as one variable increases, the other also increases; in inverse variation, as one increases, the other decreases.
