The constant of proportionality will be same as the slope of the line. Let's take two points from the line: (0,0) and (1,2)
The slope for a line that passes through two points and is:
Substitute the two points into this formula for slope and we have:
After solving and simplifying, we get
Thus, the slope of the line is 2. This means that the constant of proportionality is 2. Let me know if you need any clarifications, thanks!

Answer: 133. Im not sure that is correct because that's impossible, but I added 132 to 400 to get 532, then dived by 4. Worked it backwards to get 133.
Ln 22.5 there is your answer
