Answer:

  1. y = 2/3x

  2. P, y=-3x

Step-by-step explanation:

1. The constant k in the proportion y=kx can be found as ...

  k = y/x . . . . for any x-y pair

The first pair gives ...

  k = 2/3

So, the relation is ...

  y = 2/3x

__

2. The y-intercept is 0, so the relation is proportional.

The constant of proportionality k can be found from the graph by finding the value of y when x=1. We know that a point on the graph is (-1, 3), and we can also see that the line goes through (1, -3)

  y = -3x
