Question

Direct and inverse variation

Answer 1

Answer:

For direct variation, use the equation y = kx, where k is the constant of proportionality.

For inverse variation, use the equation y = k/x, again, with k as the constant of proportionality.

Remember that these problems might use the word 'proportion' instead of 'variation,' but it means the same thing.

Answer 2

Answer:

Direct variation

Use the equation y= kx

where,

k is the constant of proportionality.

Inverse variation

Use the equation y = k/x

Again, with k as the constant proportionality.

The word 'Proportion' instead of 'Variation' it means is a something.
