Question

The graph below shows a proportional relationship between y and z. What is the constant of proportionality y / z?

a) 1
b) 2
c) 3
d) 4

Answer 1

The constant of proportionality for a proportional relationship between y and z is approximately 2.

Step-by-step explanation:

The constant of proportionality for a proportional relationship is found by dividing the value of y by the value of z. In this case, the graph shows a proportional relationship between y and z. To find the constant of proportionality, we select any point on the graph and calculate the ratio of y to z at that point. Since the graph does not provide specific points, we can estimate the ratio based on the graph. Looking at the graph, it appears that the ratio of y to z is approximately 2. Therefore, the constant of proportionality y / z is approximately 2.
