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.)

Step-by-step 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

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
