Question

M is directly proportional to n. which equation could represent the relationship between m and n?
1.8*1/m=n
2.m*n=8
3.1/5*m=1/n
4.m=8*1/n
5.m/n=8

x and y vary directly. which equation could represent the relationship between x and y?
1.1/6*1/x=y
2.6*1/x=y
3.x=6-y
4.x=6*1/y
5.x/y=6

Answer 1

when A and B are directly proportional,

then A/B is a constant :)

Answer 2

so what do you think?

Answer 3

5?

Answer 4
