HELP WILL GIV YOU 30 POINTS BUT HELP ME
MrRa [10]

Answer:

3/4

Step-by-step explanation:

Constant of Proportionality is just a fancy way of saying slope (for a line passing through (0, 0), at least).

You can find it by looking at y/x, which will be equal at any point on the line (which is why it is a "constant").

So, for multiple points on the line:

1.5 / 2 = 3/4

3 / 4 = 3/4

4.5 / 6 = 3/4
