Question

?? help, help, quickkk, (thank you for a straight answer)

Answer 1

C

Explanation:

3/6 = 1/2

constant of proportionality = rate of change = slope and so on.

in such an equation of y = ... , this is always the factor of x.

y/x = 1/2.

the only equation for that is

C

y = 3/6 x

y/x = 3/6 = 1/2
