Question

Whether this equation represents a direct proportion? 0.4 Y = X If so,identify the value of Constant of proportionality

Answer 1

it is a direct proportion

The constant of proportionality is 0.4

Explanation:

0.4 Y = X

Direct proportion can be written as

x = ky

Where,

k = constant of proportionality

0.4 Y = X can also be written as

x = 0.4y it is a direct proportion

The constant of proportionality is 0.4
