Answer:
1/2
Explanation:
I got this wrong it gave me this step by step equation on khan I hope this helps
1 / 3
What times x gives us y?
2 / 3
If we multiply each x-value by 1 / 2 we get to each corresponding y-value:
y = 1 / 2x
3 / 3
The constant of proportionality (r) in the equation y =rx is 1 / 2
this was the exact same explanation and answer khan academy game me, so it should be right
