Find the constant of proportionality for the graph and write in the form y = kx. a) y = 1 7 x b) y = 5x c) y = 7x d) y = 35x

Find the x and y for each dot:

5,35

10,70

15,105

etc.

Divide the Y by the X:

35 / 5 = 7

70 / 10 = 7

etc.

The answer would be C) y = 7x

1. minimum

2. 6400

3. eight

hope this !

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
