Question

GRAPH:
(4 ,6) , (2 ,3) , (0,0).

Identify the constant of proportionality from the graph.

A. 2
B. 2/3
C. 3/2
D. 1/2

Answer 1

To find the constant of proportionality, we can use the formula:

constant of proportionality = change in y / change in x

Using the given points from the graph, we can calculate the change in y and change in x.

Change in y = 6 - 3 = 3
Change in x = 4 - 2 = 2

Now we can substitute these values into the formula:

constant of proportionality = 3 / 2 = 3/2

Therefore, the correct answer is C. 3/2.
