Question

This graph shows the relationship between the pounds of cheese bought at a deli and the total cost, in dollars, for the cheese. Identify the constant of proportionality represented in the graph.​

Answer 1

y = 4x

Explanation:

formula is y=kx, where k is factor of proportionality

Looking at the graph where y and x meet...

2/0.5 = 4 so 2 = 4(0.5)

Therefore, 4 is k (constant)

4=4(1)

6=4(1.5)

10=4(2.5)

and so on...
