M/n =4 identify the variation as direct, inverse, joint or combined.

m/n =4 is a direct variation

Step-by-step explanation:

m/n =4 identify the variation as direct, inverse, joint or combined

Direct variation is y=kx

Indirect variation is y=k/x

Joint variation is the combination of both direct and indirect

Multiply by 'n' on both sides

m = 4n

'm' varies directly with 'n'

So m/n =4 is a direct variation
