Which line has a constant of proportionality between Y and X of 1

Answer:
Line B
Step-by-step explanation:
The line B has a proportionality of one which you can tell because of the equation Y=1X. Simplified, this equation means that for every increase in X value, there is an equal increase in Y value. This equation can be used to find the proportionality rate of other lines such as how A is Y=2X and C is Y=1/2X.
