Question

Help meeeeeeeeeeeee!!!!!

Answer 1

5. The Constant of proportionality is found by picking two points and putting the change in y and dividing that by the change in x. in this case that is 5/1. this can be simplified to 5.

Answer 2

B

Explanation:

A constant variation graph has the following format:

`y=kx`

Where k is the constant of proportionality.

Let's pick a point from the graph, say, (1,5).

Substitute 1 for x and 5 for y:

`5=1(k)`

Simplify:

`5=k`

Therefore, the constant of proportionality is 5.

And we're done!
