Identify the constant proportionality from the graph (points: 2,3 - 4,6)
answers:
A. 1/2
B. 3/2
C. 2/3
D. 2
To find the constant proportionality, we need to find the ratio of the change in the y-values to the change in the x-values.
The change in the y-values is 6-3 = 3
The change in the x-values is 4-2 = 2
Therefore, the constant proportionality is 3/2.
The correct answer is B. 3/2.
