Answer:
1. y = 2/3x
2. P, y=-3x
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
