Question

The graph below represents the proportional relationship between the weight of objects on Earth versus their weight on the Moon. What is the constant of proportionality? (Hint: it equals the slope of the line.)

Answer 1

`(1)/(6)`

Explanation:

let constant = k, then the proportional equation must be

y=kx

as the graph we get random point through (12, 2) so x=12 and y=2, substitute to y=kx we get

2=k.12

2/12=k

1/6 = k
